Subject: mm: notifier_from_errno() cleanup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5fda1bd5b8869574dad8e1f9f71e23bf0c186274;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

mm: notifier_from_errno() cleanup

While looking at some other notifier callbacks I noticed this code could
use a simple cleanup.

notifier_from_errno() no longer needs the if (ret)/else conditional.  That
same conditional is now done in notifier_from_errno().
