Subject: mmc: omap_hsmmc: pass IRQF_ONESHOT to request_threaded_irq
From: Ming Lei <[email protected]>
commit db35f83ef47b5f180f2670d11f5f93992314ea09 upstream.
The flag of IRQF_ONESHOT should be passed to request_threaded_irq,
otherwise the following failure message should be dumped because
hardware handler is defined as NULL:
[ 3.383483] genirq: Threaded irq requested with handler=NULL and
!ONESHOT for irq 368
[ 3.392730] omap_hsmmc: probe of omap_hsmmc.0 failed with error -22
The patch fixes one kernel hang bug which is caused by mmc card
probe failure and root device can't be brought up.
