[PATCH v5 10/24] backlight: lp8788: explicitly apply PWM config extracted from pwm_args

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Call pwm_apply_args() just after requesting the PWM device so that the
polarity and period are initialized according to the information provided
in pwm_args.

This is an intermediate state, and pwm_apply_args() should be dropped as
soon as the atomic PWM infrastructure is in place and the driver makes
use of it.
