Subject: wm831x_power: Use IRQF_ONESHOT to request threaded IRQs

From: Valentin Rothberg <valentinrothberg@gmail.com>

commit 90adf98d9530054b8e665ba5a928de4307231d84 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.

scripts/coccinelle/misc/irqf_oneshot.cocci detected this issue.
