Subject: [PATCH] drm/i915: fix command parser debug print format mismatches

From: Jani Nikula <[email-masked]>
Date: Wed, 2 Apr 2014 11:24:20 +0300

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?)

Thanks for the report.
