Looking at the libdrm sources on cgit.freedesktop.org, I did not find any
specific manual on submitting patches.
But looking at the dri-list archive, dri-devel@lists.freedesktop.org is the
right list and looking at the libdrm history it looks like Emil Velikov
<emil.l.velikov@gmail.com> seems to be doing maintenance-stuff in libdrm.
And as a 3rd recipient, please also include the linux-rockchip list.
@Emil, please shout if I read that wrong :-)
Hope that helps
Heiko
