[PATCH] ASoC: imx-audmux: Remove unused .id_table

[PATCH] ASoC: imx-audmux: Remove unused .id_table

[Fabio Estevam]

Since 5.10-rc1 i.MX is a devicetree-only platform and the existing
.id_table support in this driver was only useful for old non-devicetree
platforms.

Get rid of the .id_table since it is no longer used.

Thanks!

[1/1] ASoC: imx-audmux: Remove unused .id_table
      commit: 6a8b8b582db13a18235f3b0400f103a0573c7859

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
