The patch ASoC: acpi: fix machine driver selection based on quirk has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 5c256045b87b8aa8e5bc9d2e2fdc0802351c1f99 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx> Date: Fri, 5 Jan 2018 14:55:33 -0600 Subject: [PATCH] ASoC: acpi: fix machine driver selection based on quirk MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
