[alsa-devel] [PATCH] ASoC: jz4740-i2s: Use clk_prepare_enable/clk_disable_unprepare

Lars-Peter Clausen lars at metafoo.de
Sun May 12 20:07:39 CEST 2013


In preparation to switching the jz4740 clk driver to the common clk framework
update the clk enable/disable calls to clk_prepare_enable/clk_disable_unprepare.
