[Intel-gfx] [PATCH i-g-t v2 7/7] kms_writeback: Add tests using a cloned output
Liviu Dudau

Fri Jul 14 15:18:56 UTC 2017
From: Brian Starkey <brian.starkey at arm.com>
Update the connector search to also optionally attempt to find a
non-writeback connector to clone to.
Add a subtest which is the same as writeback-check-output, but also
clones to the second connector.
