From 1d2c90425d5b0dcbf4a0fab2053d5087758b76a0 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Mon, 6 Nov 2006 21:52:16 -0500 Subject: [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.
