4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fabio Estevam <fabio.estevam@freescale.com>
commit 6c0d48cb29c29b306ba3548afb45154d22eb4d78 upstream.
Since commit 1c6c69525b40 ("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.
