Subject: "floppy: fix hibernation" causes error on resume from ram

Thanks for the hibernation fix!  Until recently I thought my floppy was
just dead.  Unfortunately, the fix seems to cause me errors on resume
from suspend to ram.  The floppy works fine afterwards, it just spams
the log.

On 2.6.30 there were no errors, and the floppy survived suspend-to-ram. 
So I guess the quick fix would be to only do the fix-up on resume from
hibernation, and not suspend-to-ram.

Thanks
Alan
