The 'Fixes' tag must be separated by the commit message by a blank
line, and you need to remove the empty line between 'Fixes' and SoB.

Additionally, on repost, please specify the target tree in the patch
subj, and wrap the commit message text to 75 chars per line (that does
not apply to the build output).

Thanks,

Paolo
