[PATCH] pcmcia: multifunction card handling fixes
s->functions needs to be initialized earlier, for the "let's see how high it increases" approach means that pcmcia_request_irq() (which makes use of this value) is confused, and might request an exclusive IRQ first even though it is not supposed to. Also, a CIS override autoloaded using the firmware loader may allow for the use of more or less functions in a multifunction card. Therefore, we may need to schedule a call to add this second function later on, or simply remove the other function (it's always the first -valid- function which reaches this codepath). Many thanks to Fabrice Bellet for debugging and testing patches. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
