iio: twl4030-madc: Pass the IRQF_ONESHOT flag
Author: Fabio Estevam <fabio.estevam@freescale.com>
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.
