de538cfc7cd649216801829daffe602f4efee08a is the first bad commit commit de538cfc7cd649216801829daffe602f4efee08a Author: Damien Lespiau <damien.lespiau@intel.com> AuthorDate: Mon Jul 7 13:30:41 2014 +0100 Commit: Damien Lespiau <damien.lespiau@intel.com> CommitDate: Mon Jul 7 17:59:52 2014 +0100 kms_plane: Make the gathering of reference CRCs test agnostic We're going to add tests for panning. Both position and panning tests share the need to grab reference CRCs of single coloured fb, so let's separate this function from the position test.
