Subject: [PATCH] drivers: power: set IRQF_ONESHOT if no primary handler is specified
Date: Thu, 19 Nov 2015 12:42:59 +0530 [thread overview]
Message-ID: <1447917179-9333-1-git-send-email-saurabh.truth@gmail.com> (raw)
If no primary handler is specified for threaded_irq then a
default one is assigned which always returns IRQ_WAKE_THREAD.
This handler requires the IRQF_ONESHOT, because the source of
interrupt is not disabled.
