Subject: ASoC: core: Return -ENOTSUPP instead of -EINVAL if mute is not supported
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=04570c628fbd5ede85d87a0b81bd19df7b13bbc4;p=~shefty%2Frdma-dev.git

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.
