The kernel patch should be in a proper format, so that it can be
merged to the upstream.  e.g. The Subject line should have a brief
description with the proper prefix for the corresponding subsystem (in
your case, something like "ASoC: amd:").  It'll follow the patch
description, as well as your proper Signed-off-by tag.

The details are found in 
  https://docs.kernel.org/process/submitting-patches.html

Could you resubmit the patch in a proper format?


thanks,
