The soundwire regmap that may be allocated during probe is not freed on
late probe failures.

Add the missing error handling.

[1/1] ASoC: codecs: wcd939x: fix regmap leak on probe failure
      commit: 86dc090f737953f16f8dc60c546ae7854690d4f6

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
