Subject: pwm: atmel: set pwm_chip can_sleep flag
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=cf3a384b3484200f45d185b2e3c7b71fd4511ea7;p=deliverable%2Flinux.git

pwm: atmel: set pwm_chip can_sleep flag

atmel_pwm_config() calls clk_get_rate() which might sleep, so we need to
set pwm_chip can_sleep flag.
