Hello,

I am working on a drm_connector scoped backlight API in Rust. I have been
looking through Hans de Goede's previous efforts on this topic to help
guide my design. My hope is to enable backlight control over external
displays through DDC or USB Monitor Control Class while also supporting
internal panels. In parallel, I would like to improve the driver
probing/selection mechanism when there are different candidates for driving
a backlight device. This initial RFC is mainly intended to sanity check
that the plumbing I have chosen for extending the DRM connector
functionality in Rust seems reasonable.

I did toss in two doc comment cleanup patches in the mix. If these need to
be re-sent individually or split due to the multiple Fixes: tags, do not
hesitate to let me know.

Thanks,
Rahul Rameshbabu
