Subject: regulator: wm831x: Pass the IRQF_ONESHOT flag
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=29454738f96233466d5bfacf86c7a8d49f79ae27;p=linux-beck.git

regulator: wm831x: Pass the IRQF_ONESHOT flag

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.
