Subject: bcma: mips: fix clearing device IRQ
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cbbc0138efe1dcd5426b8fc5d87741f5057aee72;p=linux-beck.git

bcma: mips: fix clearing device IRQ

We were using wrong IRQ number so clearing wasn't working at all.
Depending on a platform this could result in a one device having two
interrupts assigned. On BCM4706 this resulted in all IRQs being broken.
