From 72b43cf1402169e8bc088838a6db91d613c35627 Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Tue, 7 Jul 2009 18:09:48 +0200 Subject: ALSA: cmi8330: Allow MPU-401-less operation Adding MPU-401 support to cmi8330 driver could cause a regression (non-working sound) on a system where there is no free IRQ for the MPU-401 device (which is not very uncommon as this card requires two separate IRQs plus a third one for MPU-401). When MPU-401 PnP configuration fails (mostly because of unavailable IRQ), just ignore MPU-401 and continue without it.
