Subject: ASoC: remove duplicated code on pxa-ssp.c
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=fa44c077eb2a17aa6913feceb493d13f45f3fa25;p=openwrt%2Fstaging%2Fblogic.git

ASoC: remove duplicated code on pxa-ssp.c

* We don't need to write the registers twice, remove the first write.
* DAIFMT_INV switch is duplicated inside DAIFMT_FORMAT switch, move it
  out.

(This patch is for Mark's for-2.6.32 branch, I have not checked if the
code is duplicated on current 2.6.30)
