Drop remaining uses of the deprecated drmP.h in gma500 Replaced drmp.h with forward declarations or include files as relevant. Moved all include files to blocks in following order: \#include <linux/*> \#include <asm/*> \#include <drm/*> \#include "" And within each block sort the include files alphabetically.
