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.
