Subject: [PATCH] ASoC: adau1701: Use gpio_set_value_cansleep()
Date: Sun, 11 Aug 2013 15:15:58 +0100	[thread overview]
Message-ID: <1376230558-16248-1-git-send-email-broonie@kernel.org> (raw)

From: Mark Brown <broonie@linaro.org>

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.
