Subject: ALSA: emux: remove unused redundant variable p2
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=41e4b7dc6e1b6d717edb8679759c2bde138f78a9;p=openwrt%2Fstaging%2Fblogic.git

ALSA: emux: remove unused redundant variable p2

The variable p2 is being assigned but never used, it is redundant
and can be safely removed.  Cleans up clang warning: Value stored to
'p2' is never read.
