[PATCH v2 1/3] ASoC: SDCA: export sdca_find_entity_by_label() helper

[shumingf]

From: Shuming Fan <shumingf@realtek.com>

Export the sdca_find_entity_by_label() helper so that codec drivers can
locate SDCA entities by their labels.

Be good to make sure you are CCing at least
patches@opensource.cirrus.com on SDCA patches, safer that I don't
miss them on the list that way.

But the patch looks good:

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-7.3

Thanks!

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
