Subject: [PATCH] ASoC: tas2770: Add missing bias level power states
Git-commit: 4272caf34aa4699eca8e6e7f4a8e5ea2bde275c9
Patch-mainline: v5.10-rc1
References: git-fixes
Add the BIAS_STANDBY and BIAS_PREPARE to the set_bias_level or else the
driver will return -EINVAL which is not correct as they are valid
states.
Fixes: 1a476abc723e6 ("tas2770: add tas2770 smart PA kernel driver")
