Any devices that fare better in this regard?

Not really, no. For manufacturers it is faster to just write the drivers once for their chip, and release them targeting to an exact Linux kernel version rather than actually writing good enough code that it goes through the LKML process and gets merged into mainline. It costs money to update the drivers later on and it especially costs money to mainline them later on.

Nobody's asking for mainline submissions though. Just publishing the drivers source code under a FLOSS licence when they stop supporting it would be enough to let the community take over the maintenance.
