Subject: genirq: Fix misplaced status update in irq_disable()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a61d825808a0ce9935afebc225dcd602d5339e14;p=linux-beck.git

genirq: Fix misplaced status update in irq_disable()

We lazy disable interrupt lines, so only mark the line masked, when
the chip provides an irq_disable callback.
