Date: Fri, 22 Oct 2010 11:51:28 -0700 From: Greg KH <gregkh@...e.de> To: linux-kernel@...r.kernel.org, stable@...nel.org Cc: stable-review@...nel.org, torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, Mark Brown <broonie@...nsource.wolfsonmicro.com>, Samuel Ortiz <sameo@...ux.intel.com> Subject: [054/103] mfd: Ignore non-GPIO IRQs when setting wm831x IRQ types 2.6.35-stable review patch. If anyone has any objections, please let us know. ------------------ From: Mark Brown <broonie@...nsource.wolfsonmicro.com> commit c9d66d3515bbb0ad8062721487de7ade02d2b936 upstream. 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.
