X-Git-Tag: v2.6.28-rc1~720^2~148
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=acdfc9e305b8320c5dee714a08be022441b58c44;p=linux-2.6-omap-h63xx.git

ALSA: ASoC: WM8903 I2C cleanups

Fix a few issues identified by Jean Delvare:

 - Add missing newline to error display.
 - Return an error when we fail to locate the I2C adaptor.
 - Remove the static wm8903_i2c_device Jean suggested, it's redundant.
