From 97d22306daf83df207223b401820236ee1c0a2e6 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Thu, 13 Dec 2012 18:51:10 +0000 Subject: [PATCH] brcm47xx: return the real irq number in bcma_core_irq The irq signal numbers that are send by the cpu are increased by 2 from the number programmed into the mips core by bcma. Return the irq number on which the irqs are send in bcma_core_irq() now.
