Subject: printk: rename printk_sched to printk_deferred
X-Git-Tag: upstream/snapshot3+hdmi~1931
X-Git-Url: http://review.tizen.org/git/?p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git;a=commitdiff_plain;h=a8554e0d8b51719e1bb90855a242533fecb4dbdc

printk: rename printk_sched to printk_deferred

commit aac74dc495456412c4130a1167ce4beb6c1f0b38 upstream.

After learning we'll need some sort of deferred printk functionality in
the timekeeping core, Peter suggested we rename the printk_sched function
so it can be reused by needed subsystems.

This only changes the function name. No logic changes.
