Subject[ 27/83] ASoC: cs42l52: fix the return value of cs42l52_set_fmt()
Date
3.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>

commit 5c855c8e2be67f2d5a989ef1190098f924f9f820 upstream.

Fix the return value of cs42l52_set_fmt() when clock inversion is
not allowed and also remove the useless variable ret.

[We had been assigning to ret but then ignoring the value we assgined
