Subject: [PATCH 4.9 06/66] drm/vc4: Fix memory leak of the CRTC state.

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eric Anholt <eric@...olt.net>

commit 7622b25543665567d8830a63210385b7d705924b upstream.

The underscores variant frees the pointers inside, while the
no-underscores variant calls underscores and then frees the struct.

Fixes: d8dbf44f13b9 ("drm/vc4: Make the CRTCs cooperate on allocating display lists.")
