https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v5.17 Quite a few fixes here, including an unusually large set in the core spurred on by various testing efforts as well as the usual small driver fixes. There are quite a few fixes for out of bounds writes in both the core and the various Qualcomm drivers, plus a couple of fixes for locking in the DPCM code.

2022-01-08Input: zinitix - handle proper supply namesLinus Walleij
The supply names of the Zinitix touchscreen were a bit confused, the new bindings rectifies this. To deal with old and new devicetrees, first check if we have "vddo" and in case that exists assume the old supply names. Else go and look for the new ones. We cannot just get the regulators since we would get an OK and a dummy regulator: we need to check explicitly for the old supply name. Use struct device *dev as a local variable instead of the I2C client since the device is what we are actually obtaining the resources from.

2022-01-08Input: zinitix - make sure the IRQ is allocated before it gets enabledNikita Travkin
Since irq request is the last thing in the driver probe, it happens later than the input device registration. This means that there is a small time window where if the open method is called the driver will attempt to enable not yet available irq. Fix that by moving the irq request before the input device registration.

2022-01-08Input: axp20x-pek - revert "always register interrupt handlers" changeHans de Goede
The power button on Cherry Trail systems with an AXP288 PMIC is connected to both the power button pin of the PMIC as well as to a power button GPIO on the Cherry Trail SoC itself. This leads to double power button event reporting which is a problem. Since reporting power button presses through the PMIC is not supported on all PMICs used on Cherry Trail systems, we want to keep the GPIO power button events, so the axp20x-pek code checks for the presence of a GPIO power button and in that case does not register its input-device. On most systems the GPIO power button also can wake-up the system from suspend, so the axp20x-pek driver would also not register its interrupt handler. But on some systems there was a bug causing wakeup by the GPIO power button handler to not work. Commit 9747070c11d6 ("Input: axp20x-pek - always register interrupt handlers") was added as a work around for this registering the axp20x-pek interrupts, but not the input-device on Cherry Trail systems. In the mean time the root-cause of the GPIO power button wakeup events not working has been found and fixed by the "pinctrl: cherryview: Do not allow the same interrupt line to be used by 2 pins" patch, so this is no longer necessary. This reverts the workaround going back to only registering the interrupt handlers on systems where we also register the input-device.

2021-12-12Input: silead - add support for EFI-embedded fw using different min/max ↵Hans de Goede
coordinates Unfortunately, at the time of writing this commit message, we have been unable to get permission from Silead, or from device OEMs, to distribute the necessary Silead firmware files in linux-firmware. On a whole bunch of devices the UEFI BIOS code contains a touchscreen driver, which contains an embedded copy of the firmware. The fw-loader code has a "platform" fallback mechanism, which together with info on the firmware from drivers/platform/x86/touchscreen_dmi.c will use the firmware from the UEFI driver when the firmware is missing from /lib/firmware. This makes the touchscreen work OOTB without users needing to manually download the firmware. The firmware bundled with the original Windows/Android is usually newer then the firmware in the UEFI driver and it is better calibrated. This better calibration can lead to significant differences in the reported min/max coordinates. Add support for a new (optional) "silead,efi-fw-min-max" property which provides a set of alternative min/max values to use for the x/y axis when the EFI embedded firmware is used. The new property is only used on (x86) devices which do not use devicetree, IOW it is not used in actual devicetree files. The devicetree-bindings maintainers have requested properties like these to not be added to the devicetree-bindings, so the new property is deliberately not added to the existing silead devicetree-bindings documentation.

2021-12-06Input: ff-core - correct magnitude setting for rumble compatibilityCharles Keepax
When converting a rumble into a periodic effect, for compatibility, the magnitude is effectively calculated using: magnitude = max(strong_rubble / 3 + weak_rubble / 6, 0x7fff); The rumble magnitudes are both u16 and the resulting magnitude is s16. The max is presumably an attempt to limit the result of the calculation to the maximum possible magnitude for the s16 result, and thus should be a min. However in the case of strong = weak = 0xffff, the result of the first part of the calculation is 0x7fff, meaning that the min would be redundant anyway, so simply remove the current max.

2021-12-06Input: goodix - try not to touch the reset-pin on x86/ACPI devicesHans de Goede
Unless the controller is not responding at boot or after suspend/resume, the driver never resets the controller on x86/ACPI platforms. The driver still requesting the reset pin at probe() though in case it needs it. Until now the driver has always requested the reset pin with GPIOD_IN as type. The idea being to put the pin in high-impedance mode to save power until the driver actually wants to issue a reset. But this means that just requesting the pin can cause issues, since requesting it in another mode then GPIOD_ASIS may cause the pinctrl driver to touch the pin settings. We have already had issues before due to a bug in the pinctrl-cherryview.c driver which has been fixed in commit 921daeeca91b ("pinctrl: cherryview: Preserve CHV_PADCTRL1_INVRXTX_TXDATA flag on GPIOs"). And now it turns out that requesting the reset-pin as GPIOD_IN also stops the touchscreen from working on the GPD P2 max mini-laptop. The behavior of putting the pin in high-impedance mode relies on there being some external pull-up to keep it high and there seems to be no pull-up on the GPD P2 max, causing things to break. This commit fixes this by requesting the reset pin as is when using the x86/ACPI code paths to lookup the GPIOs; and by not dropping it back into input-mode in case the driver does end up issuing a reset for error-recovery.

2021-11-29Input: elantech - fix stack out of bound access in elantech_change_report_id()Andrea Righi
The array param[] in elantech_change_report_id() must be at least 3 bytes, because elantech_read_reg_params() is calling ps2_command() with PSMOUSE_CMD_GETINFO, that is going to access 3 bytes from param[], but it's defined in the stack as an array of 2 bytes, therefore we have a potential stack out-of-bounds access here, also confirmed by KASAN: [ 6.512374] BUG: KASAN: stack-out-of-bounds in __ps2_command+0x372/0x7e0 [ 6.512397] Read of size 1 at addr ffff8881024d77c2 by task kworker/2:1/118 [ 6.512416] CPU: 2 PID: 118 Comm: kworker/2:1 Not tainted 5.13.0-22-generic #22+arighi20211110 [ 6.512428] Hardware name: LENOVO 20T8000QGE/20T8000QGE, BIOS R1AET32W (1.08 ) 08/14/2020 [ 6.512436] Workqueue: events_long serio_handle_event [ 6.512453] Call Trace: [ 6.512462] show_stack+0x52/0x58 [ 6.512474] dump_stack+0xa1/0xd3 [ 6.512487] print_address_description.constprop.0+0x1d/0x140 [ 6.512502] ? __ps2_command+0x372/0x7e0 [ 6.512516] __kasan_report.cold+0x7d/0x112 [ 6.512527] ? _raw_write_lock_irq+0x20/0xd0 [ 6.512539] ? __ps2_command+0x372/0x7e0 [ 6.512552] kasan_report+0x3c/0x50 [ 6.512564] __asan_load1+0x6a/0x70 [ 6.512575] __ps2_command+0x372/0x7e0 [ 6.512589] ? ps2_drain+0x240/0x240 [ 6.512601] ? dev_printk_emit+0xa2/0xd3 [ 6.512612] ? dev_vprintk_emit+0xc5/0xc5 [ 6.512621] ? __kasan_check_write+0x14/0x20 [ 6.512634] ? mutex_lock+0x8f/0xe0 [ 6.512643] ? __mutex_lock_slowpath+0x20/0x20 [ 6.512655] ps2_command+0x52/0x90 [ 6.512670] elantech_ps2_command+0x4f/0xc0 [psmouse] [ 6.512734] elantech_change_report_id+0x1e6/0x256 [psmouse] [ 6.512799] ? elantech_report_trackpoint.constprop.0.cold+0xd/0xd [psmouse] [ 6.512863] ? ps2_command+0x7f/0x90 [ 6.512877] elantech_query_info.cold+0x6bd/0x9ed [psmouse] [ 6.512943] ? elantech_setup_ps2+0x460/0x460 [psmouse] [ 6.513005] ? psmouse_reset+0x69/0xb0 [psmouse] [ 6.513064] ? psmouse_attr_set_helper+0x2a0/0x2a0 [psmouse] [ 6.513122] ? phys_pmd_init+0x30e/0x521 [ 6.513137] elantech_init+0x8a/0x200 [psmouse] [ 6.513200] ? elantech_init_ps2+0xf0/0xf0 [psmouse] [ 6.513249] ? elantech_query_info+0x440/0x440 [psmouse] [ 6.513296] ? synaptics_send_cmd+0x60/0x60 [psmouse] [ 6.513342] ? elantech_query_info+0x440/0x440 [psmouse] [ 6.513388] ? psmouse_try_protocol+0x11e/0x170 [psmouse] [ 6.513432] psmouse_extensions+0x65d/0x6e0 [psmouse] [ 6.513476] ? psmouse_try_protocol+0x170/0x170 [psmouse] [ 6.513519] ? mutex_unlock+0x22/0x40 [ 6.513526] ? ps2_command+0x7f/0x90 [ 6.513536] ? psmouse_probe+0xa3/0xf0 [psmouse] [ 6.513580] psmouse_switch_protocol+0x27d/0x2e0 [psmouse] [ 6.513624] psmouse_connect+0x272/0x530 [psmouse] [ 6.513669] serio_driver_probe+0x55/0x70 [ 6.513679] really_probe+0x190/0x720 [ 6.513689] driver_probe_device+0x160/0x1f0 [ 6.513697] device_driver_attach+0x119/0x130 [ 6.513705] ? device_driver_attach+0x130/0x130 [ 6.513713] __driver_attach+0xe7/0x1a0 [ 6.513720] ? device_driver_attach+0x130/0x130 [ 6.513728] bus_for_each_dev+0xfb/0x150 [ 6.513738] ? subsys_dev_iter_exit+0x10/0x10 [ 6.513748] ? _raw_write_unlock_bh+0x30/0x30 [ 6.513757] driver_attach+0x2d/0x40 [ 6.513764] serio_handle_event+0x199/0x3d0 [ 6.513775] process_one_work+0x471/0x740 [ 6.513785] worker_thread+0x2d2/0x790 [ 6.513794] ? process_one_work+0x740/0x740 [ 6.513802] kthread+0x1b4/0x1e0 [ 6.513809] ? set_kthread_struct+0x80/0x80 [ 6.513816] ret_from_fork+0x22/0x30 [ 6.513832] The buggy address belongs to the page: [ 6.513838] page:00000000bc35e189 refcount:0 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x1024d7 [ 6.513847] flags: 0x17ffffc0000000(node=0|zone=2|lastcpupid=0x1fffff) [ 6.513860] raw: 0017ffffc0000000 dead000000000100 dead000000000122 0000000000000000 [ 6.513867] raw: 0000000000000000 0000000000000000 00000000ffffffff 0000000000000000 [ 6.513872] page dumped because: kasan: bad access detected [ 6.513879] addr ffff8881024d77c2 is located in stack of task kworker/2:1/118 at offset 34 in frame: [ 6.513887] elantech_change_report_id+0x0/0x256 [psmouse] [ 6.513941] this frame has 1 object: [ 6.513947] [32, 34) 'param' [ 6.513956] Memory state around the buggy address: [ 6.513962] ffff8881024d7680: f2 f2 f2 f2 f2 00 00 f3 f3 00 00 00 00 00 00 00 [ 6.513969] ffff8881024d7700: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 6.513976] >ffff8881024d7780: 00 00 00 00 f1 f1 f1 f1 02 f3 f3 f3 00 00 00 00 [ 6.513982] ^ [ 6.513988] ffff8881024d7800: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 6.513995] ffff8881024d7880: 00 f1 f1 f1 f1 03 f2 03 f2 03 f3 f3 f3 00 00 00 [ 6.514000] ================================================================== Define param[] in elantech_change_report_id() as an array of 3 bytes to prevent the out-of-bounds access in the stack.

2021-11-28Input: iqs626a - prohibit inlining of channel parsing functionsJeff LaBundy
Some automated builds report a stack frame size in excess of 2 kB for iqs626_probe(); the culprit appears to be the call to iqs626_parse_prop(). To solve this problem, specify noinline_for_stack for all of the iqs626_parse_*() helper functions which are called inside a for loop within iqs626_parse_prop(). As a result, a build with '-Wframe-larger-than' as low as 512 is free of any such warnings.

2021-11-28Input: i8042 - add deferred probe supportTakashi Iwai
We've got a bug report about the non-working keyboard on ASUS ZenBook UX425UA. It seems that the PS/2 device isn't ready immediately at boot but takes some seconds to get ready. Until now, the only workaround is to defer the probe, but it's available only when the driver is a module. However, many distros, including openSUSE as in the original report, build the PS/2 input drivers into kernel, hence it won't work easily. This patch adds the support for the deferred probe for i8042 stuff as a workaround of the problem above. When the deferred probe mode is enabled and the device couldn't be probed, it'll be repeated with the standard deferred probe mechanism. The deferred probe mode is enabled either via the new option i8042.probe_defer or via the quirk table entry. As of this patch, the quirk table contains only ASUS ZenBook UX425UA. The deferred probe part is based on Fabio's initial work.

2021-11-23xen: add "not_essential" flag to struct xenbus_driverJuergen Gross
When booting the xenbus driver will wait for PV devices to have connected to their backends before continuing. The timeout is different between essential and non-essential devices. Non-essential devices are identified by their nodenames directly in the xenbus driver, which requires to update this list in case a new device type being non-essential is added (this was missed for several types in the past). In order to avoid this problem, add a "not_essential" flag to struct xenbus_driver which can be set to "true" by the respective frontend. Set this flag for the frontends currently regarded to be not essential (vkbs and vfb) and use it for testing in the xenbus driver.

Modern devices may redraw display at 60 Hz, make sure we have one input sample per one frame. Reduce sample period to 15ms, so we would get up to 66.6 samples per second, although realistically with all the jitter and extra scheduling wiggle room, we would end up just above 60 samples per second. This should be a good compromise between sampling too often and sampling too seldom.

2021-11-09Input: ili210x - improve polled sample spacingMarek Vasut
Currently the ili210x driver implements a threaded interrupt handler which starts upon edge on the interrupt line, and then polls the touch controller for samples. Every time a sample is obtained from the controller, the thread function checks whether further polling is required, and if so, waits fixed amount of time before polling for next sample. The delay between consecutive samples can thus vary greatly, because the I2C transfer required to retrieve the sample from the controller takes different amount of time on different platforms. Furthermore, different models of the touch controllers supported by this driver require different delays during retrieval of samples too. Instead of waiting fixed amount of time before polling for next sample, determine how much time passed since the beginning of sampling cycle and then wait only the remaining amount of time within the sampling cycle. This makes the driver deliver samples with equal spacing between them.
