   ASoC: mediatek: add the .probe() callback in mt2701_afe_pcm_dai_component

has been applied to the asoc tree at


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.

Subject: [PATCH] ASoC: mediatek: add the .probe() callback in

For the sake of uniformity, this patch adds a callback mt2701_afe_pcm_probe()
in mt2701_afe_pcm_dai_component to retrieve the regmap - the canonical way to
obtain the pointer..

Doing so, we could switch to use devm_snd_soc_register_component() to register
the component driver.
