From e18eca4303c67ac58c75e72c7318e9709188f40d Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Tue, 14 Sep 2010 14:54:47 +0300 Subject: [PATCH 1/3] ASoC: tlv320aic3x: Use snd_soc_read and snd_soc_write Start phasing out aic3x_read_reg_cache, aic3x_write_reg_cache, aic3x_read and aic3x_write calls in order to switch to soc-cache helpers. This patch replaces aic3x_read_reg_cache and aic3x_write with snd_soc_read and snd_soc_write. This is basically null-op since .read and .write in soc_codec_dev_aic3x points to aic3x_read_reg_cache and aic3x_write.
