Subject: drm: i915: Wait for fences on new fb, not old
From: Daniel Stone <[email protected]>
commit 1fb3672eaf6ec95fb34c22734feffd6041531c5b upstream.
The previous code would wait for fences on the framebuffer from the old plane state to complete, rather than the new, so you would see tearing everywhere. Fix this to wait on the new state before we make it active.
