sched/core: Remove dead statement in __schedule()

lgebyungchulpark · Ingo Molnar · commit 3223d052b79e · 2016-02-17T09:32:03.000+01:00
Remove an unnecessary assignment of variable not used any more. ( This has no runtime effects as GCC is smart enough to optimize this out. ) Signed-off-by: Byungchul Park <byungchul.park@lge.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Link: http://lkml.kernel.org/r/1455159578-17256-1-git-send-email-byungchul.park@lge.com [ Edited the changelog. ] Signed-off-by: Ingo Molnar <mingo@kernel.org>
