Subject: sched: Remove noop in alloc_rt_sched_group()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1437f5bca3c2d162f058cba37dfbeb20f619040d;p=linux-beck.git

sched: Remove noop in alloc_rt_sched_group()

The rq varible, though computed for each possible cpu, has nothing to
do in the function, so it can be removed.

This also eliminates a build warning.
