platform/x86: dell-wmi-base: Handle electronic privacy screen on/off events

2025-10-28T15:12:00Z

Add handling for events for the electronic privacy screen found on some models (e.g. Dell Latitude 7300) being toggled on/off. Emit KEY_EPRIVACY_SCREEN_OFF / KEY_EPRIVACY_SCREEN_ON events for this so that userspace can show the usual on-screen-display (OSD) notification for eprivacy screen on/off to the user.

platform/x86: int3472: Fix double free of GPIO device during unregister

2025-10-28T15:06:14Z

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.

media: v4l2-subdev / pdx86: int3472: Use "privacy" as con_id for the privacy LED

2025-10-24T09:16:26Z

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.
