Subject: ASoC: core: Return -ENOTSUPP instead of -EINVAL if mute is not supported
X-Git-Tag: firefly_0821_release~3680^2~2691^2~9^2~98

ASoC: core: Return -ENOTSUPP instead of -EINVAL if mute is not supported

This helps us ignore errors in callers if the operation failed due to not
being available as opposed to an error.
