2021-09-02pwm: ab8500: Fix register offset calculation to not depend on probe orderUwe Kleine-König
The assumption that lead to commit 5e5da1e9fbee ("pwm: ab8500: Explicitly allocate pwm chip base dynamically") was wrong: The pwm-ab8500 devices are not directly instantiated from device tree, but from the ab8500 mfd driver. So the pdev->id isn't -1, but a number between 1 and 3. Now that pwmchip ids are always allocated dynamically, this cannot easily be reverted. Introduce a new member in the driver data struct that tracks the hardware id and use this to calculate the register offset. Side-note: Using chip->base to calculate the offset was never robust because if there was already a PWM with id 1 at the time ab8500-pwm.1 was probed, the associated pwmchip would get assigned chip->base = 2 (or something bigger).

2021-09-02pwm: atmel: Rework tracking updates pending in hardwareUwe Kleine-König
This improves the driver's behavior in several ways: - The lock is held for shorter periods and so a channel that is currently waited for doesn't block disabling another channel. - It's easier to understand because the procedure is split into more semantic units and documentation is improved - A channel is only set to pending when such an event is actually scheduled in hardware (by writing the CUPD register). - Also wait in .get_state() to report the last configured state instead of (maybe) the previous one. This fixes the read back duty cycle and so prevents a warning being emitted when PWM_DEBUG is on. Tested on an AriettaG25.

2021-09-02ACPI: PM: s2idle: Run both AMD and Microsoft methods if both are supportedMario Limonciello
It was reported that on "HP ENVY x360" that power LED does not come back, certain keys like brightness controls do not work, and the fan never spins up, even under load on 5.14 final. In analysis of the SSDT it's clear that the Microsoft UUID doesn't provide functional support, but rather the AMD UUID should be supporting this system. Because this is a gap in the expected logic, we checked back with internal team. The conclusion was that on Windows AMD uPEP *does* run even when Microsoft UUID present, but most OEM systems have adopted value of "0x3" for supported functions and hence nothing runs. Henceforth add support for running both Microsoft and AMD methods. This approach will also allow the same logic on Intel systems if desired at a future time as well by pulling the evaluation of `lps0_dsm_func_mask_microsoft` out of the `if` block for `acpi_s2idle_vendor_amd`.

2021-09-02PCI: VMD: ACPI: Make ACPI companion lookup work for VMD busRafael J. Wysocki
On some systems, in order to get to the deepest low-power state of the platform (which may be necessary to save significant enough amounts of energy while suspended to idle. for example), devices on the PCI bus exposed by the VMD driver need to be power-managed via ACPI. However, the layout of the ACPI namespace below the VMD controller device object does not reflect the layout of the PCI bus under the VMD host bridge, so in order to identify the ACPI companion objects for the devices on that bus, it is necessary to use a special _ADR encoding on the ACPI side. In other words, acpi_pci_find_companion() does not work for these devices, so it needs to be amended with a special lookup logic specific to the VMD bus. Address this issue by allowing the VMD driver to temporarily install an ACPI companion lookup hook containing the code matching the devices on the VMD PCI bus with the corresponding objects in the ACPI namespace.

2021-09-02firmware: dmi: Move product_sku info to the end of the modaliasHans de Goede
Commit e26f023e01ef ("firmware/dmi: Include product_sku info to modalias") added a new field to the modalias in the middle of the modalias, breaking some existing udev/hwdb matches on the whole modalias without a wildcard ('*') in between the pvr and rvn fields. All modalias matches in e.g. : https://github.com/systemd/systemd/blob/main/hwdb.d/60-sensor.hwdb deliberately end in ':*' so that new fields can be added at *the end* of the modalias, but adding a new field in the middle like this breaks things. Move the new sku field to the end of the modalias to fix some hwdb entries no longer matching. The new sku field has already been put to use in 2 new hwdb entries: sensor:modalias:platform:HID-SENSOR-200073:dmi:*svnDell*:sku0A3E:* ACCEL_LOCATION=base sensor:modalias:platform:HID-SENSOR-200073:dmi:*svnDell*:sku0B0B:* ACCEL_LOCATION=base The wildcard use before and after the sku in these matches means that they should keep working with the sku moved to the end. Note that there is a second instance of in essence the same problem, commit f5152f4ded3c ("firmware/dmi: Report DMI Bios & EC firmware release") Added 2 new br and efr fields in the middle of the modalias. This too breaks some hwdb modalias matches, but this has gone unnoticed for over a year. So some newer hwdb modalias matches actually depend on these fields being in the middle of the string. Moving these to the end now would break 3 hwdb entries, while fixing 8 entries. Since there is no good answer for the new br and efr fields I have chosen to leave these as is. Instead I'll submit a hwdb update to put a wildcard at the place where these fields may or may not be present depending on the kernel version.

2021-09-02net: hso: add failure handler for add_net_deviceZiyang Xuan
If the network devices connected to the system beyond HSO_MAX_NET_DEVICES. add_net_device() in hso_create_net_device() will be failed for the network_table is full. It will lead to business failure which rely on network_table, for example, hso_suspend() and hso_resume(). It will also lead to memory leak because resource release process can not search the hso_device object from network_table in hso_free_interface(). Add failure handler for add_net_device() in hso_create_net_device() to solve the above problems.

2021-09-02net: dsa: lantiq_gswip: fix maximum frame lengthJan Hoffmann
Currently, outgoing packets larger than 1496 bytes are dropped when tagged VLAN is used on a switch port. Add the frame check sequence length to the value of the register GSWIP_MAC_FLEN to fix this. This matches the lantiq_ppa vendor driver, which uses a value consisting of 1518 bytes for the MAC frame, plus the lengths of special tag and VLAN tags.

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux Pull printk updates from Petr Mladek: - Optionally, provide an index of possible printk messages via <debugfs>/printk/index/. It can be used when monitoring important kernel messages on a farm of various hosts. The monitor has to be updated when some messages has changed or are not longer available by a newly deployed kernel. - Add printk.console_no_auto_verbose boot parameter. It allows to generate crash dump even with slow consoles in a reasonable time frame. - Remove printk_safe buffers. The messages are always stored directly to the main logbuffer, even in NMI or recursive context. Also it allows to serialize syslog operations by a mutex instead of a spin lock. - Misc clean up and build fixes. * tag 'printk-for-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: printk/index: Fix -Wunused-function warning lib/nmi_backtrace: Serialize even messages about idle CPUs printk: Add printk.console_no_auto_verbose boot parameter printk: Remove console_silent() lib/test_scanf: Handle n_bits == 0 in random tests printk: syslog: close window between wait and read printk: convert @syslog_lock to mutex printk: remove NMI tracking printk: remove safe buffers printk: track/limit recursion lib/nmi_backtrace: explicitly serialize banner and regs printk: Move the printk() kerneldoc comment to its new home printk/index: Fix warning about missing prototypes MIPS/asm/printk: Fix build failure caused by printk printk: index: Add indexing support to dev_printk printk: Userspace format indexing support printk: Rework parse_prefix into printk_parse_prefix printk: Straighten out log_flags into printk_info_flags string_helpers: Escape double quotes in escape_special printk/console: Check consistent sequence number when handling race in console_unlock()
