[PATCH] i4l make PCMCIA for all cards working with shared IRQ
most current laptops do not work without allowing shared cardbus IRQs. This patch enables IRQ sharing, so these cards work again. This was tested with shared and none shared cardbus IRQs on different laptops without problems. Signed-off-by: Karsten Keil <kkeil@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
