mmc: of_mmc_spi: Add IRQF_ONESHOT to interrupt flags

saurabh-sengar · storulf · commit 60b71f607796 · 2015-12-22T11:32:17.000+01:00
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
