HID: Add quirk to ignore the touchscreen battery on HP ENVY 15-eu0556ng

2023-10-05T10:50:35+00:00

Like various other devices using similar hardware, this model reports a
perpetually empty battery (0-1%).

Join the others and apply HID_BATTERY_QUIRK_IGNORE.

HID: intel-ish-hid: ipc: Disable and reenable ACPI GPE bit

2023-10-05T10:50:35+00:00

The EHL (Elkhart Lake) based platforms provide a OOB (Out of band)
service, which allows to wakup device when the system is in S5 (Soft-Off
state). This OOB service can be enabled/disabled from BIOS settings. When
enabled, the ISH device gets PME wake capability. To enable PME wakeup,
driver also needs to enable ACPI GPE bit.

On resume, BIOS will clear the wakeup bit. So driver need to re-enable it
in resume function to keep the next wakeup capability. But this BIOS
clearing of wakeup bit doesn't decrement internal OS GPE reference count,
so this reenabling on every resume will cause reference count to overflow.

So first disable and reenable ACPI GPE bit using acpi_disable_gpe().

HID: sony: remove duplicate NULL check before calling usb_free_urb()

2023-10-05T10:50:35+00:00

usb_free_urb() does the NULL check itself, so there is no need to duplicate
it prior to calling.

HID: nintendo: reinitialize USB Pro Controller after resuming from suspend

2023-10-05T10:50:34+00:00

When suspending the computer, a Switch Pro Controller connected via USB will
lose its internal status. However, because the USB connection was technically
never lost, when resuming the computer, the driver will attempt to communicate
with the controller as if nothing happened (and fail).
Because of this, the user was forced to manually disconnect the controller
(or to press the sync button on the controller to power it off), so that it
can be re-initialized.

With this patch, the controller will be automatically re-initialized after
resuming from suspend.

HID: nvidia-shield: Fix some missing function calls() in the probe error handling path

2023-10-05T10:50:34+00:00

The commit in Fixes updated the error handling path of
thunderstrike_create() and the remove function but not the error handling
path of shield_probe(), should an error occur after a successful
thunderstrike_create() call.

Add the missing calls.

HID: nvidia-shield: Fix a missing led_classdev_unregister() in the probe error handling path

The commit in Fixes updated the error handling path of
thunderstrike_create() and the remove function but not the error handling
path of shield_probe(), should an error occur after a successful
thunderstrike_create() call.

Add the missing call. Make sure it is safe to call in the probe error
handling path by preventing the led_classdev from attempting to set the LED
brightness to the off state on unregister.

HID: holtek: fix slab-out-of-bounds Write in holtek_kbd_input_event

2023-09-18T15:13:01+00:00

There is a slab-out-of-bounds Write bug in hid-holtek-kbd driver.
The problem is the driver assumes the device must have an input
but some malicious devices violate this assumption.

Fix this by checking hid_device's input is non-empty before its usage.
