Title
media: i2c: ar0521: Use cansleep version of gpiod_set_value()
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: i2c: ar0521: Use cansleep version of gpiod_set_value()
If we use GPIO reset from I2C port expander, we must use *_cansleep()
variant of GPIO functions.
This was not done in ar0521_power_on()/ar0521_power_off() functions.
Let's fix that.
