From: Sebastian Andrzej Siewior Date: Thu, 7 Jul 2011 20:32:17 +0000 (+0200) Subject: irq: Always set IRQF_ONESHOT if no primary handler is specified X-Git-Tag: firefly_0821_release~3680^2~4631^2~1 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=f3637a5f2e2eb391ff5757bc83fb5de8f9726464;p=firefly-linux-kernel-4.4.55.git irq: Always set IRQF_ONESHOT if no primary handler is specified If no primary handler is specified then a default one is assigned which always returns IRQ_WAKE_THREAD. This handler requires the IRQF_ONESHOT flag on LEVEL / EIO typed irqs because the source of interrupt is not disabled. Since it is required for those users and there is no difference for others it makes sense to add this flag unconditionally.
