This passes the address of the pointer "&punit_ipcdev" when the intent was to pass the pointer itself "punit_ipcdev" (without the ampersand). This means that the: complete(&ipcdev->cmd_complete); in intel_punit_ioc() will write to a wrong memory address corrupting it.

2025-11-21platform: arm64: thinkpad-t14s-ec: sleep after EC accessSebastian Reichel1-0/+4
The ACPI ECRD and ECWR functions have a 10ms sleep at the end. It turns out, that this is sometimes needed to avoid I2C transmission failures, especially for functions doing regmap_update_bits (and thus read + write shortly after each other). This fixes problems like the following appearing in the kernel log: leds platform::micmute: Setting an LED's brightness failed (-6) leds platform::kbd_backlight: Setting an LED's brightness failed (-6) The ACPI QEVT function used to read the interrupt status register also has a 10ms sleep at the end. Without that there are problems with reading multiple events following directly after each other resulting in the following error message being logged: thinkpad-t14s-ec 4-0028: Failed to read event Fixes: 60b7ab6ce030 ("platform: arm64: thinkpad-t14s-ec: new driver") Signed-off-by: Sebastian Reichel <sre@kernel.org> Link: https://patch.msgid.link/20251119-thinkpad-t14s-ec-improvements-v2-2-441219857c02@kernel.org Reviewed-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>
2025-11-21platform: arm64: thinkpad-t14s-ec: fix IRQ race conditionSebastian Reichel1-6/+6
Fix a race condition, that an input key related interrupt might be triggered before the input handler has been registered, which results in a NULL pointer dereference. This can happen if the user enables the keyboard backlight shortly before the driver is being probed. This fixes the following backtrace visible in dmesg: Unable to handle kernel NULL pointer dereference at virtual address 00000000000000e0 ...

2025-11-10platform/x86: msi-wmi-platform: Fix typo in WMI GUIDArmin Wolf1-1/+1
The WMI driver core only supports GUID strings containing only uppercase characters, however the GUID string used by the msi-wmi-platform driver contains a single lowercase character. This prevents the WMI driver core from matching said driver to its WMI device. Fix this by turning the lowercase character into a uppercase character. Also update the WMI driver development guide to warn about this.

2025-11-10platform/x86: msi-wmi-platform: Only load on MSI devicesArmin Wolf2-1/+41
It turns out that the GUID used by the msi-wmi-platform driver (ABBC0F60-8EA1-11D1-00A0-C90629100000) is not unique, but was instead copied from the WIndows Driver Samples. This means that this driver could load on devices from other manufacturers that also copied this GUID, potentially causing hardware errors. Prevent this by only loading on devices whitelisted via DMI. The DMI matches where taken from the msi-ec driver.

The Xbox Ally features a Van Gogh SoC that has spurious interrupts during resume. We get the following logs: atkbd_receive_byte: 20 callbacks suppressed atkbd serio0: Spurious ACK on isa0060/serio0. Some program might be trying to access hardware directly. So, add the spurious_8042 quirk for it. It does not have a keyboard, so this does not result in any functional loss.

The ROG Xbox Ally (non-X) SoC features a similar architecture to the Steam Deck. While the Steam Deck supports S3 (s2idle causes a crash), this support was dropped by the Xbox Ally which only S0ix suspend. Since the handler is missing here, this causes the device to not suspend and the AMD GPU driver to crash while trying to resume afterwards due to a power hang.

2025-10-28platform/x86: int3472: Fix double free of GPIO device during unregisterQiu Wenbo1-4/+1
regulator_unregister() already frees the associated GPIO device. On ThinkPad X9 (Lunar Lake), this causes a double free issue that leads to random failures when other drivers (typically Intel THC) attempt to allocate interrupts. The root cause is that the reference count of the pinctrl_intel_platform module unexpectedly drops to zero when this driver defers its probe. This behavior can also be reproduced by unloading the module directly. Fix the issue by removing the redundant release of the GPIO device during regulator unregistration.

During DT-binding review for extending the V4L2 camera sensor privacy LED support to systems using devicetree, it has come up that having a "-led" suffix for the LED name / con_id is undesirable since it already is clear that it is a LED. Drop the "-led" suffix from the con_id in both the lookup table in the int3472 code, as well as from the con_id led_get() argument in the v4l2-subdev code.

Add support for the Acer Iconia One 8 A1-840 (non FHD version) tablet. This tablet has the usual issues for tablets shipped with Android as factory OS. The DSDT is broken in various ways, so i2c_clients for various devices as well as the INT3496 platform-device for OTG extcon handling need to be instantiated manually by x86-android-tablets. This tablet is special in that it is the first time a Bay Trail device has been found to use the Dollar Cove TI PMIC and the first time that the PMIC's Coulomb Counter is used as fuel-gauge.
