From 1a52598c4b1d358af7ac562defd98c395842dbdd Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Sat, 16 May 2015 15:42:12 -0300 Subject: [PATCH] mfd: wm831x-auxadc: 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.
