Subject: CVE-2024-42087: drm/panel: ilitek-ili9881c: Fix warning with GPIO controllers that sleep

Description
===========

In the Linux kernel, the following vulnerability has been resolved:

drm/panel: ilitek-ili9881c: Fix warning with GPIO controllers that sleep

The ilitek-ili9881c controls the reset GPIO using the non-sleeping
gpiod_set_value() function. This complains loudly when the GPIO
controller needs to sleep. As the caller can sleep, use
gpiod_set_value_cansleep() to fix the issue.

The Linux kernel CVE team has assigned CVE-2024-42087 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
