Subject: [PATCH] mmc: of_mmc_spi: Add IRQF_ONESHOT to interrupt flags
Date: Wed, 25 Nov 2015 23:56:24 +0530	[thread overview]
Message-ID: <1448475984-11332-1-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
