[PATCH] ASoC: codecs: wcd93xx: fix object added to multiple drivers

[Krzysztof Kozlowski]

Three Qualcomm audio codecs (WCD9355, WCD934x and WCD938x) use the same
object file wcd-clsh-v2.o leading to warnings:

  Makefile: wcd-clsh-v2.o is added to multiple modules: snd-soc-wcd9335 snd-soc-wcd934x snd-soc-wcd938x

Convert the wcd-clsh-v2.o to a module to solve it.

Thanks!

[1/1] ASoC: codecs: wcd93xx: fix object added to multiple drivers
      commit: 11b0b802f8e38d48ca74d520028add81263f003e

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
