[Intel-gfx] [PATCH 03/10] drm/i915: Write out crc frame counts in hex

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

The crc code assumes that the printed frame counter value takes
exactly 8 characters. The counter is a 32bit value, so to fit
it into 8 characters we need to print it in hex, in decimal it
would take 10 characters.

This obviously needs a corresponding change in intel-gpu-tools.
