ASoC: CX20442: fix issues pointed out by subsystem maintainer
The patch fixes some checkpatch identified issues and adds a comment about line discipline interaction to my driver code, as requested by Mark on my inital submission (thank you Mark for applying my imperfect patch anyway). It also fixes MODULE_ALIAS mismatch as used in my machine driver. Signed-off-by: Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
