Subject: tick/sched: Don't clear ts::next_tick again in can_stop_idle_tick()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=60313c21c33abc08108bdd60390fa89563977e64;p=linux.git

tick/sched: Don't clear ts::next_tick again in can_stop_idle_tick()

The tick sched structure is already cleared from tick_cancel_sched_timer(),
so there is no need to clear that field again.
