Subject: sched: Fix comment for sched_info_depart
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=13b62e46d5407c7d619aea1dc9c3e0991b631b57;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

sched: Fix comment for sched_info_depart

sched_info_depart seems to be only called from
sched_info_switch(), so only on involuntary task switch.

Fix the comment to match.
