So you can add my Reviewed-by: Pali Roh=C3=A1r to this patch. Anyway, BYD show Linux as supported OS for their devices. It is really=20 rude from BYD that they show Linux as supported OS, but Linux driver is=20 reverse-engineered by community and they do not want to cooperate and at=20 least provide some useful documentation for detection... =2D-=20 Pali Roh=C3=A1r pali.rohar@gmail.com --nextPart2066006.hKQSnr5iPu Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEABECAAYFAlgnb/UACgkQi/DJPQPkQ1K4twCghQJAV65L9bVypvuCiAkGZ9Qf mJ0An1/VkdUcxuaFXpHhV9C1GwLhIWeP =g+iS -----END PGP SIGNATURE----- --nextPart2066006.hKQSnr5iPu--
