The patch titled
pata_cs5530: suspend/resume support
has been removed from the -mm tree. Its filename was
pata_cs5530-suspend-resume-support.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: pata_cs5530: suspend/resume support
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
The 5530 needs various set up performing both at init time and resume time.
To keep the code clean the common setup code is moved into a new function and
called from both handlers.
