[PATCH 0/2] ASoC: mt6359: Fix regulator_dev_lookup() fails for id "LDO_VAUD18"

[Jiaxin Yu]

This series fixed "LDO_VAUD18-supply" regulator register fail.
We can see the error log "mt6359-sound supply LDO_VAUD18 not found, using
dummy regulator" when register the DAPM widget "LDO_VAUD18"
Otherwise, the power can not be turned on correctly when recording.

[PATCH 1/2] ASoC: mediatek: mt6359: Fix regulator_dev_lookup() fails for id "LDO_VAUD18"

[Jiaxin Yu]

Mt6359 platform device is instantiated by mfd_add_devices(). In the
case, dev->of_node is NULL so that always fails to get the regulator_dev.

Use regualator-name "vaud18" that in dts node instead of
"LDO_VAUD19-supply". So that we can get regulator_dev through
regulator_lookup_by_name() directly.

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
