Hi Laurent,

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.
Seems something buggy happened to the patchset, this patch doesn't appear
in the cover letter and insn't numbered...
