Is there actually a need for sort of not platform_data but universal

established doing that already in a generic, not-platform-specific
way
that can go in all distros and so on nicely. Maybe this is just my
impoverished imagination and people do want, say, some kinds of USB
mice
to operate at higher DPI or whatever when plugged in a specific board
because it is that board.
Except that vid/pid are the -WRONG- way to do that. Your device is
on-board, the proper way to identify it uniquely is it's topological
location, ie path of HW port numbers.
Thanks Ben.
I'll go change that VID/PID stuff in my patches right away.
