Subject: ASoC: Return correct codec clock in s3c64xx-i2s
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b1cd6b9ec7c749ddfad628c8c12659591ae195e6;p=mv-sheeva.git

ASoC: Return correct codec clock in s3c64xx-i2s

Instead of always returnig pointer to the 'audio-bus' clock,
check which clock is used to generate internal clocks and
then return it's pointer.
