[igt-dev] [PATCH i-g-t 3/3] tests/kms_flip: Request the initial vbl count with RELATIVE instead of ABSOLUTE

[Ville Syrjala]

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

Asking for the initial vblank count by specifying and absolute vblank count of 0
doesn't make much sense. Switch to a relative query instead.

It doesn't look like we care about lining up on the first vblank boundary so
we can just drop the NEXTONMISS flag. Only the relative timestamps of the
events will matter.

v2: Drop the NEXTONMISS (Daniel)
