Subject: [PATCH][V2] ASoC: ti: davinci-mcasp: remove redundant assignment to variable ret

From: Colin Ian King <colin.king@...onical.com>

The assignment to ret is redundant as it is not used in the error
return path and hence can be removed.

Addresses-Coverity: ("Unused value")

V2: explicitly return NULL to improve readability. Thanks to Dan Carpenter for
    suggesting this improvement.
