Hi Vladislav,
we are almost there.
When submitting/applying a patch, we do run ./script/checkpatch.pl on
the final patch.
This gives us here 2 warnings (inlined below)
Also, can you versionize your submissions (use `-v` in git
format-patch: `git format-patch -v3 HEAD`).

checkpatch.pl complains here:
WARNING: Missing Signed-off-by: line by nominal patch author 'h0tw4t3r
<hotwater438@xxxxxxxxxxxx>'
Either:
- change your git settings and reset the author (git commit --amend
--reset-author)
- just drop this "From:" from the patch from git format-patch

IIRC Andy said Co-developped-by: Hans de Goede <...> here. Does that stand Hans?

WARNING: please, no spaces at the start of a line

Thanks for fixing these 3 minor issues, and we will be able to merge it :)
Cheers,
