Backport DRM_CRTC_IN_VBLANK for wlroots >= 0.7 on FreeBSD 11.*

jbeich commented 4 years ago

Required by https://github.com/swaywm/wlroots/pull/1738 (or https://github.com/freebsd/freebsd-ports/commit/ab8a57f405f4) to fix the following error. Tested on -CURRENT (with drm-v4.16 build fixes) and Sway 1.4.

$ sway -dc /dev/null

LGTM

Have you tested this on 11?

jbeich commented 4 years ago

No, I don't use FreeBSD 11. Regression is unlikely because it's a new feature without new function calls and only 1 consumer (wlroots).

Obsolete after https://github.com/freebsd/freebsd-ports/commit/620968a43a5f.
