[Intel-gfx] [PATCH v3 2/8] drm/i915/display: Move the commit_tail() disable sequence to commit_modeset_disables() hook
Manasi Navare

Mon Jun 24 21:08:44 UTC 2019
Create a new hook commit_modeset_disables() consistent with the naming
in drm atomic helpers and similar to the commit_modeset_enables() hook.
This helps better organize the disable sequence in atomic_commit_tail()
and move that to this disable hook.
No functional change
