From e86fa21b77f4ef840213ecd33230c7c16879a4ac Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 28 Sep 2016 23:25:00 +0100 Subject: [PATCH] drm: Restore lost drm_framebuffer_unreference in drm_mode_page_flip_ioctl Commit 43968d7b806d ("drm: Extract drm_plane.[hc]") was not the simple cut'n'paste we presumed, somehow it introduced a leak of the page flip target's framebuffer.
