[PATCH v2 0/3] ASoC: mediatek: Remove redundant code and add sample rate checker of MT7986 SoC

[Maso Huang]

Changes in v2:
 - devide v1 patch [1/2] into v2 [1/3] [2/3] with appropriate title and description
 - refine error log based on reviewer's suggestions [3/3]

1. Drop the remove callback of mt7986_wm8960.
2. Remove the mt7986_wm8960_priv structure
3. Add sample rate checker.
Patches are based on broonie tree "for-next" branch.

[2/3] ASoC: mediatek: mt7986: remove the mt7986_wm8960_priv structure
      commit: 0f10adb0ed0c0d74f8bc5facf2c70bc515210295
[3/3] ASoC: mediatek: mt7986: add sample rate checker
      commit: 0e20929434080aa87614fa0135c97bb9337ece27

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,
