[alsa-devel] [PATCH] ASoC: da732x: Replace hw_read usage with snd_soc_read()
From: Mark Brown broonie@linaro.org
Pre-merge code was using direct hw_read() calls as an out of framework way of doing volatile register I/O when not using regmap. This has never functioned correctly in mainline due to the regmap conversion, the hw_read() implementation still does caching. In order to facilitate removal of the subsystem level I/O code convert to use snd_soc_read(), there should be no functional impact.
