Subject: [PATCH 1/6] drm/vc4: bo: Add a managed action to cleanup the cache
Date: Thu, 29 Oct 2020 20:00:59 +0100 [thread overview]
Message-ID: <20201029190104.2181730-1-maxime@cerno.tech> (raw)
The BO cache needs to be cleaned up using vc4_bo_cache_destroy, but it's
not used consistently (vc4_drv's bind calls it in its error path, but
doesn't in unbind), and we can make that automatic through a managed
action. Let's remove the requirement to call vc4_bo_cache_destroy.
Fixes: c826a6e10644 ("drm/vc4: Add a BO cache.")
