Expecting every developer to keep abreast of linux-next and the tens of
thousands of patches it gets just isn't realisitic.

The embedded platforms I develop on won't run linux-next. Continuously
porting them to linux-next is simply impossible. The man hours required to
do that would be staggering.

The pool of testers available to a driver that requires running linux-next
is going to be orders of magnitude less that a driver that can be compiled
out of tree against 2.6.19 to 2.6.27.

This seems perfectly reasonable to me.

Somtimes maintainers aren't interested in the drivers.....
