Subject: [PATCH] drm/core: Do not call drm_framebuffer_remove internally during teardown.
Date: Wed,  9 Sep 2015 13:46:21 +0200	[thread overview]
Message-ID: <1441799181-15404-1-git-send-email-maarten.lankhorst@linux.intel.com> (raw)

This may cause issues because encoders are already destroyed so removing
active primaries may use freed memory. Instead free the fb directly,
ignoring refcount.
