At the next time you submit a patch, please add Cc to maintainer and subsystem ML. Otherwise it'd be easily overlooked.

When VGA_SWITCHEROO support is enabled hda_intel initialises the HDMI audio device on the current VGA device. When it's not enabled it only initialises the HDMI device on the default VGA adaptor, this means secondary cards get no audio support which is very unhelpful for multi-seat!

With this patch, when SUPPORT_VGA_SWITCHEROO is disabled hda_intel initialises all HDMI audio devices, not just the default VGA.

OK, it must be fixed indeed. The bug was introduced due to the change in VGA-switcheroo side -- originally check_hdmi_disabled() really checked the VGA-switcheroo state, so it returned the correct value in the earlier version.

In anyway, your patch looks almost OK, but it'd be better to move ifdef and simplify like below. Could you check whether it works for you?

Also, please give a patch that is applicable directly via git-am. Apparently you created it via git show. Instead, use git-format-patch or use --pretty=email for git-show. Or, send the patch directly via git-send-email.

thanks,

Takashi
