[Intel-gfx] [PATCH v1.1 2/5] drm/atomic: Make prepare_fb/cleanup_fb only take state, v2.
Maarten Lankhorst
maarten.lankhorst at linux.intel.com
Thu Jul 16 07:13:08 PDT 2015
This removes the need to separately track fb changes i915.
Changes since v1:
- Add dri-devel to cc.
- Fix a check in intel's prepare and cleanup fb to take rotation
into account.
Cc: dri-devel at lists.freedesktop.org
