Subject: staging/android: remove pointless sync_timeline_signal at destroy phase
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=84288db5ca3fdac8d5a4bc730cc0b20144ddaa46;p=linux-beck.git

staging/android: remove pointless sync_timeline_signal at destroy phase

All changes to timeline value come through the user via
sync_timeline_signal() calls. When sync_timeline_destroy() is called no
changes on timeline->value happens hence call sync_timeline_signal() with
no increment is pointless.
