Subject: [PATCH 419/454] media: ov5647: Use gpiod_set_value_cansleep
|
|
|
|
All calls to the gpio library are in contexts that can sleep,
|
|
therefore there is no issue with having those GPIOs controlled
|
|
by controllers which require sleeping (eg I2C GPIO expanders).
|
|
|
|
Switch to using gpiod_set_value_cansleep instead of gpiod_set_value
|
|
to avoid triggering the warning in gpiolib should the GPIO
|
|
controller need to sleep.
|
