2017-10-31platform/x86: ideapad-laptop: Add Lenovo Yoga 920-13IKB to no_hw_rfkill dmi listPhilipp Hug
The Lenovo Yoga 920-13IKB does not have a hw rfkill switch, and trying to read the hw rfkill switch through the ideapad module causes it to always report as blocked. This commit adds the Lenovo Yoga 920-13IKB to the no_hw_rfkill dmi list, fixing the WiFI breakage.

Several function prototypes for the set/get functions defined by module_param_call() have a slightly wrong argument types. This fixes those in an effort to clean up the calls when running under type-enforced compiler instrumentation for CFI. This is the result of running the following semantic patch: @match_module_param_call_function@ declarer name module_param_call; identifier _name, _set_func, _get_func; expression _arg, _mode; @@ module_param_call(_name, _set_func, _get_func, _arg, _mode); @fix_set_prototype depends on match_module_param_call_function@ identifier match_module_param_call_function._set_func; identifier _val, _param; type _val_type, _param_type; @@ int _set_func( -_val_type _val +const char * _val , -_param_type _param +const struct kernel_param * _param ) { ... } @fix_get_prototype depends on match_module_param_call_function@ identifier match_module_param_call_function._get_func; identifier _val, _param; type _val_type, _param_type; @@ int _get_func( -_val_type _val +char * _val , -_param_type _param +const struct kernel_param * _param ) { ... } Two additional by-hand changes are included for places where the above Coccinelle script didn't notice them: drivers/platform/x86/thinkpad_acpi.c fs/lockd/svc.c Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Jessica Yu <jeyu@kernel.org>
2017-10-30platform/x86: fujitsu-laptop: Fix radio LED detectionMichał Kępień
Radio LED detection method implemented in commit 4f62568c1fcf ("fujitsu-laptop: Support radio LED") turned out to be incorrect as it causes a radio LED to be erroneously detected on a Fujitsu Lifebook E751 which has a slide switch (and thus no radio LED). Use bit 17 of flags_supported (the value returned by method S000 of ACPI device FUJ02E3) to determine whether a radio LED is present as it seems to be a more reliable indicator, based on comparing DSDT tables of four Fujitsu Lifebook models (E744, E751, S7110, S8420).

2017-10-27platform/x86: hp_accel: Add quirk for HP ProBook 440 G4Osama Khan
Added support for HP ProBook 440 G4 laptops by including the accelerometer orientation quirk for that device. Testing was performed based on the axis orientation guidelines here: https://www.kernel.org/doc/Documentation/misc-devices/lis3lv02d which states "If the left side is elevated, X increases (becomes positive)". When tested, on lifting the left edge, x values became increasingly negative thus indicating an inverted x-axis on the installed lis3lv02d chip. This was compensated by adding an entry for this device in hp_accel.c specifying the quirk as x_inverted. The patch was tested on a ProBook 440 G4 device and x-axis as well as y and z-axis values are now generated as per spec.

2017-10-27platform/x86: intel_turbo_max_3: Add Skylake platformSrinivas Pandruvada
Ev Kontsevoy reported that he can't see the presence of "/proc/sys/kernel/sched_itmt_enabled" on i9-7900x with Asrock x299 Taichi system even if he enabled "Turbo 3.0" in the BIOS. The problem is that even if one core max is 200MHz more than others, the current implementation couldn't enumerate that with the way the system is configured. The system by default configured for legacy mode (no HWP or speed shift technology), in this mode only way we can enumerate via the mail box interface as implemented in this driver. We were planing to only use this driver for Broadwell, but we need to extend this because some Skylake system has same issue as Braodwell systems. On this system BIOS allows to change to HWP mode, where we expect that we can enumerate favored core with ACPI-CPPC. But on this system the core priority is 0xff for all cores in CPPC object. So this is not an option. Hence this change allows Skylake systems to be enumerate favored core similar to Broadwell in legacy mode.

2017-10-01platform/x86: thinkpad_acpi: Implement tablet mode using GMMS methodBenjamin Berg
Many thinkpad laptops and convertibles provide the GMMS method to resolve how far the laptop has been opened and whether it has been converted into tablet mode. This allows reporting a more precise tablet mode state to userspace. The current implementation only reports a summarized tablet mode state which is triggered as soon as the input devices become unusable as they are folded away from the display. This will work on all models where the CMMD method was used previously and it may also work in other cases. Thanks to Peter Zhang of Lenovo for providing information on how to use the GMMS method to query the tablet mode.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Round one of new device support, features and cleanup for IIO in the 4.15 cycle. Note there is a misc driver drop in here given we have support in IIO and the feeling is no one will care. A large part of this series is a boiler plate removal series avoiding the need to explicitly provide THIS_MODULE in various locations. It's very dull but touches all drivers. New device support * ad5446 - add ids to support compatible parts DAC081S101, DAC101S101, DAC121S101. - add the dac7512 id and drop the misc driver as feeling is no one is using it (was introduced for a board that is long obsolete) * mt6577 - add bindings for mt2712 which is fully compatible with other supported parts. * st_pressure - add support for LPS33HW and LPS35HW with bindings (ids mostly). New features * ccs811 - Add support for the data ready trigger. * mma8452 - remove artifical restriction on supporting multiple event types at the same time. * tcs3472 - support out of threshold events Core and tree wide cleanup * Use macro magic to remove the need to provide THIS_MODULE as part of struct iio_info or struct iio_trigger_ops. This is similar to work done in a number of other subsystems (e.g. i2c, spi). All drivers are fixed and then the fields in these structures are removed. This will cause build failures for out of tree drivers and any new drivers that cross with this work going into the kernel. Note mostly done with a coccinelle patch, included in the series on the mailing list but not merged as the fields no longer exist in the structures so the any hold outs will cause a build failure. Cleanups * ads1015 - avoid writing config register when it doesn't change. - add 10% to conversion wait time as it seems it is sometimes a little small. * ade7753 - replace use of core mlock with a local lock. This is part of a long term effort to make the use of mlock opaque and single purpose. * ade7759 - expand the use of buf_lock to cover previous mlock cases. This is a slightly nicer solution to the same issue as in ade7753. * cros_ec - drop an unused variable * inv_mpu6050 - add a missing break in a switch for consistency - not actual bug, - make some local arrays static to save on object code size. * max5481 - drop manual setting of the spi module owner as handled by the spi core. * max5487 - drop manual setting of the spi module owner as handled by the spi core. * max9611 - drop explicit setting of the i2c module owner as handled by the i2c core. * mcp320x - speed up reads on single channel devices, - drop unused of_device_id data elements, - document the struct mcp320x, - improve binding docs to reflect restrictions on spi setup and to make it explicit that the reference regulator is needed. * mma8452 - symbolic to octal permissions, - unsigned to unsigned int. * st_lsm6dsx - avoid setting odr values multiple times, - drop config of LIR as it is only ever set to the existing defaults, - drop rounding configuration as it only ever matches the defaults. * ti-ads8688 - drop manual setting of the spi module owner as handled by the spi core. * tsl2x7x - constify the i2c_device_id, - cleanup limit checks to avoid static checker warnings (and generally have nicer code).
2017-09-22platform/x86: intel-hid: Power button suspend on Dell Latitude 7275Jérôme de Bretagne
On Dell Latitude 7275 the 5-button array is not exposed in the ACPI tables, but notififies are still sent to the Intel HID device object (device ID INT33D5) in response to power button actions. They were ignored as the intel-hid driver was not prepared to take care of them until recently. Power button wakeup from suspend-to-idle was added in: commit 635173a17b03 ("intel-hid: Wake up Dell Latitude 7275 from suspend-to-idle") However power button suspend doesn't work yet on this platform so it would be good to add it also. On the affected platform (for which priv->array is NULL), add a new upfront check against the power button press notification (0xCE) to notify_handler(), outside the wakeup mode this time, which allows reporting the power button press event and triggers the suspend. Also catch and ignore the corresponding power button release notification (0xCF) to stop it from being reported as an "unknown event" in the logs.

2017-09-20platform/x86: Add driver to force WMI Thunderbolt controller power statusMario Limonciello
Current implementations of Intel Thunderbolt controllers will go into a low power mode when not in use. Many machines containing these controllers also have a GPIO wired up that can force the controller awake. This is offered via a ACPI-WMI interface intended to be manipulated by a userspace utility. This mechanism is provided by Intel to OEMs to include in BIOS. It uses an industry wide GUID that is populated in a separate _WDG entry with no binary MOF. This interface allows software such as fwupd to wake up thunderbolt controllers to query the firmware version or flash new firmware.
