ASoC: acpi: fix machine driver selection based on quirk
The ACPI/machine-driver code refactoring introduced in 4.13 introduced a regression for cases where we need a DMI-based quirk to select the machine driver (the BIOS reports an invalid HID). The fix is just to make sure the results of the quirk are actually used. Fixes: 54746dabf770 ('ASoC: Improve machine driver selection based on quirk data') Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=96691 Tested-by: Nicole Færber <nicole.faerber@dpin.de> Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org
