Hi Joe,

Thanks for the info.

The original driver was written before Florian became the
framebuffer maintainer. The subsystem had no real maintainer
at the time, which is why it went via Andrew.

Hmm, perhaps author is a better term than maintainer here. Any
patches should still go via the framebuffer maintainer, Florian,
but it would be useful in many cases for the original and/or
most regular commit author to also get Cc'ed since in many
cases they will have a better understanding of the code, even
if the aren't "maintaining" it.
