[alsa-devel] [PATCH v3 0/2] ASoC: Intel: ACPI-related fixes
The first two patches in the v2 series were merged, but these last two were not.
As agreed with Andy and Vinod, there will be a follow-up patch to replace snd_soc_acpi_find_name_from_hid() with acpi_dev_get_dev_name(), as well as the introduction of a helper for the search loops.
Changes since v2: rename constant per Vinod's suggestion removed redundant comment on name
Changes since v1: cleaned-up quirk handling, fixed merge mistake added Andy's Reviewed-by tag on patch 2 added 4th patch to add new constant dependent on ACPI_ID_LEN

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

it'll go away in all machine drivers with the next cleanup (addition of a helper)

The patch
ASoC: acpi: remove hard-coded i2c-device name length
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
