[PATCH v2 7/9] ASoC: codecs: convert existing I2C client drivers to use I2C core runtime PM

From: Mika Westerberg
Date: Wed Sep 11 2013 - 11:35:13 EST


The I2C core now prepares runtime PM on behalf of the I2C client device, so
only thing the driver needs to do is to call pm_runtime_put() at the end of
its ->probe().

This patch converts ASoC codec drivers to use this model.
