The patch titled
PM: Rework struct platform_suspend_ops fixup
has been removed from the -mm tree. Its filename was
pm-rework-struct-platform_suspend_ops-fixup.patch
This patch was dropped because it was folded into pm-rework-struct-platform_suspend_ops.patch
------------------------------------------------------
Subject: PM: Rework struct platform_suspend_ops fixup
From: Rafael J. Wysocki <rjw@xxxxxxx>
A recently merged powerpc update has overlapped with the changes introduced by
the following patches:
pm-rename-struct-pm_ops-and-related-things.patch
pm-rework-struct-platform_suspend_ops.patch
As a result, mpc5200 and lite5200 need to be modified to follow the reworked
suspend core.
Thanks to Joseph Fannin <jfannin@xxxxxxxxx> for reporting the problem and
helping to fix it.
