From e02bc29b2cfa7806830d6da8b2322cddd67e8dfe Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Wed, 24 Apr 2019 11:04:13 +0200 Subject: drm/sun4i: Unbind components before releasing DRM and memory Our components may still be using the DRM device driver (if only to access our driver's private data), so make sure to unbind them before the final drm_dev_put. Also release our reserved memory after component unbind instead of before to match reverse creation order.
