From c9d66d3515bbb0ad8062721487de7ade02d2b936 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 16 Aug 2010 20:26:51 +0100 Subject: [PATCH] mfd: Ignore non-GPIO IRQs when setting wm831x IRQ types The driver was originally tested with an additional patch which made this unneeded but that patch had issuges and got lost on the way to mainline, causing problems when the errors are reported.
