this driver compiles fine everywhere which
means we can use linux-next to compile it
for us frequently.
By dropping the arch dependency, we also
ensure driver writers don't add virtual
arch-depdencies to the driver by e.g. using

A static count of transfer descriptors was used everywhere in the driver
with the fixed number 5. This patch adds a define, named TD_PAGE_COUNT,
and replaces all users of this value. This way its possible to have only
one parameter to change and limit the amount of buffer pointers per TD.
