From: Fabio Estevam <fabio.estevam@freescale.com>
Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail.
So pass the IRQF_ONESHOT flag in this case.
The semantic patch that makes this change is available in scripts/coccinelle/misc/irqf_oneshot.cocci.
