X-Git-Tag: firefly_0821_release~176^2~4889^2~176^2~61^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9190aeb4ecbdcab7d66d186c207f76d09b41d082;p=firefly-linux-kernel-4.4.55.git

ASoC: adau1701: Use gpio_set_value_cansleep()

The GPIO manipulation done by this driver is never in atomic context so
we can use gpio_set_value_cansleep() and support GPIOs that can't be set
from atomic context.
