The patch titled
floppy: fix hibernation
has been removed from the -mm tree. Its filename was
floppy-fix-hibernation.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: floppy: fix hibernation
From: Ondrej Zary <linux@xxxxxxxxxxxxxxxxxxxx>
Based on Ingo Molnar's patch from 2006, this makes the floppy work after
resume from hibernation, at least on my machine.
This fix resets the floppy controller on resume. It was experimentally
determined to bring the controller back to life - we don't really know why
it works.
floppy_init() does the same thing at boot/modprobe time.
