Drop the cast from the pointer diff to fix:

drivers/gpu/drm/i915/i915_cmd_parser.c:405:4: warning: format '%td' expects argument of type 'ptrdiff_t', but argument 5 has type 'long unsigned int' [-Wformat]

While at it, use %u for u32.

Randy, try as I might, I wasn't able to coerce gcc to spit out that warning. Please enlighten me! (Does this fix the warn?)

Yes, it does. Thanks.
