Subject: sched/core: Remove dead statement in __schedule()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3223d052b79eb9b620d170584c417d60a8bfd649;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sched/core: Remove dead statement in __schedule()

Remove an unnecessary assignment of variable not used any more.

( This has no runtime effects as GCC is smart enough to optimize
  this out. )
