1# These are various fixes needed to make the psb kernel driver build against
2# 2.6.33.2.
3# The Makefile patch is specific to the Poky environment - the external kernel
4# module build expects the kernel tree it's building against to have fixdep
5# and modpost built, which isn't the case here. So, the modules rule makes
6# sure that they are built before the module is built.
7# Aside from that, the changes involve adding missing header files and
8# compensating for a structure field changing name and type.
