Subject: ASoC: twl6040: Pass the IRQF_ONESHOT flag
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=208ba89b402d4f63a1352ae289fb8428cb92e7ec;p=deliverable%2Flinux.git

ASoC: twl6040: Pass the IRQF_ONESHOT flag

Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("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.
