From ff10fca5ceacf7bc59636f5ab808e775d1717167 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Fri, 22 Oct 2010 08:46:36 +0200 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.
