Subject: [PATCH 3/4] ASoC: wm5110: Use async writes
Date: Thu, 12 Dec 2013 11:07:40 +0000	[thread overview]
Message-ID: <1386846461-32325-3-git-send-email-broonie@kernel.org> (raw)
In-Reply-To: <1386846461-32325-1-git-send-email-broonie@kernel.org>

From: Mark Brown <broonie@linaro.org>

When writing the patch write to the device asynchronously, allowing better
performance when used with a bus like SPI which supports this by
minimising the need to context switch back to the driver to get the
next bit of data.
