Yes, that line is superfluous -- sorry about that. Could you please pull
from

git://git.kernel.org/pub/scm/linux/kernel/git/brodo/pcmcia-2.6.git urgent

for the two attached patches, please?

Subject: [PATCH] pcmcia: IOCARD is also required for using IRQs

Dave Hinds pointed out to me that 37979e1546a7 will break b43 and
ray_cs, as IOCARD is not -- as the name would suggest -- only needed
for cards using IO ports. Instead, as it re-deines several pins, it
is also required for using interrupts.
