[alsa-devel] [PATCH] ASoC: avoid unused variable warning for rt5659_acpi_match
The newly added rt5659 codec driver unconditionally defines an ACPI device match table but then uses ACPI_PTR() to remove the only reference to it, so we get a harmless build warning:
sound/soc/codecs/rt5659.c:4200:30: warning: 'rt5659_acpi_match' defined but not used [-Wunused-variable] static struct acpi_device_id rt5659_acpi_match[] = {
This changes both the OF match table and the ACPI match table to follow the same style, using ACPI_PTR/of_match_ptr to make the reference conditional, and using an #ifdef to hide the table. This also adds the missing MODULE_DEVICE_TABLE for the OF case and adapts the formatting to the same style.

The patch
ASoC: rt5659: avoid unused variable warning for rt5659_acpi_match
has been applied to the asoc tree at
git://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
