    Subject[ 85/94] mmc: omap_hsmmc: pass IRQF_ONESHOT to request_threaded_irq
    3.3-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Ming Lei <ming.lei@canonical.com>

    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.
