From 0b07939cbfdd05bed0c5ec01b8b25493e6ecd34c Mon Sep 17 00:00:00 2001 From: Giedrius Rekasius Date: Sun, 25 May 2014 15:23:31 +0100 Subject: [PATCH] sched: Remove redundant assignment to "rt_rq" in update_curr_rt(...) Variable "rt_rq" is used only in block "for_each_sched_rt_entity" so the value assigned to it at the beginning of the update_curr_rt(...) gets overwritten without ever being read. Remove redundant assignment and move variable declaration to the block in which it is being used.
