Subject: [PATCH] ASoC: codecs: ad193x: Use regmap_multi_reg_write() when initializing
Git-commit: eaba5585944e6d692828bca701c9362f60172b8a
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518

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