[PATCH] ALSA: hda-intel - Disable MSI support by default
Disable MSI support on HD-audio driver as default since there are too many broken devices. The module option is changed from disable_msi to enable_msi, too. For turning MSI support on, pass enable_msi=1, instead. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
