Subject: bug in AT91 MCI suspend routines
From: Anti Sullin <anti.sullin@xxxxxxxxxxxxxx>
This patch fixes a bug in AT91 mmc host driver, that enables the wakeup
from suspend on card detection pin even if the card detect pin is not
available (==0). If not card detection pin is defined, IRQ0 == FIQ gets
enabled and if some activity is present on that pin, the system gets a FIQ
request, that causes a crash.
Original patch from Anti Sullin reviewed by Andrew Victor and
Marc Pignat ; thank you to all of you.
