[PATCH] ASoC: codecs: remove unneeded variable: "ret"

[Gu Shengxian <gushengxian507419@gmail.com>]

From: Gu Shengxian <gushengxian@yulong.com>

The variable: "ret" is only defined and returned.
So it could be removed.
Fix some spelling mistakes.

Signed-off-by: Gu Shengxian <gushengxian@yulong.com>
