[PATCH] ASoC: codecs: ad193x: Use regmap_multi_reg_write() when initializing

[Codrin Ciubotariu]

Using regmap_multi_reg_write() when we set the default values for our
registers makes the code smaller and easier to read.

LGTM.  Thanks.

Applied "ASoC: codecs: ad193x: Use regmap_multi_reg_write() when initializing" to the asoc tree

[Mark Brown]

The patch

   ASoC: codecs: ad193x: Use regmap_multi_reg_write() when initializing

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4

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

Subject: [PATCH] ASoC: codecs: ad193x: Use regmap_multi_reg_write() when
 initializing

Using regmap_multi_reg_write() when we set the default values for our
registers makes the code smaller and easier to read.
