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

[Laurent Pinchart]

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.
