Subject: [PATCH 1/1] ASoC: codecs: add support for ES8326
The ES8326 codec is not compatible with ES8316 and requires a dedicated driver.
Signed-off-by: David Yang <yangxiaohua@xxxxxxxxxxxxxxxx>
You need to copy maintainers (added in CC:), and you're also missing a
Signed-off-by when sending patches developed by someone else.
Also please use git send-email, it looks like the indentations were
removed by your email client.
