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.

From: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com 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.

Replace snd_soc_acpi_check_hid() with the generic acpi_dev_present() and remove the now unused snd_soc_acpi_check_hid function. This should have no functional change.

Same problem as with previous machine drivers, the codec dai uses a hard-coded name of "i2c-ESSX8316:00" but ACPI provides "i2c-ESSX8316:01" in some systems.

Fix by overriding the hard-coded value with the codec name derived from the HID information

this looks good, but I though we had few other places where this was done, esp the BSW based chromebooks, if so would it make send to have a macro in soc-acpi which updates the dai name based on the result from snd_soc_acpi_find_name_from_hid()

nitpicking, thats a very long name :(

how about SND_ACPI_I2C_ID_LEN, we can drop SOC. And replace DEVICE_NAME with ID

Fine with me. Andy do you concur or have a more precise suggestion?
