Subject: genirq: Use raw_spinlock_irq() in irq_set_affinity_notifier()
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9d3faec60b1303fbec53d7a9b48a8c0fc5ae029b;p=thirdparty%2Flinux.git

genirq: Use raw_spinlock_irq() in irq_set_affinity_notifier()

Since irq_set_affinity_notifier() may sleep, interrupts are enabled. So
raw_spinlock_irqsave() can be replaced with raw_spinlock_irq().
