Subject: iio: twl4030-madc: Pass the IRQF_ONESHOT flag
From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>
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.
