Subject: [PATCH] drm: Use the driver's gem_object_free function from CMA
|
|
helpers.
|
|
|
|
VC4 wraps the CMA objects in its own structures, so it needs to do its
|
|
own teardown (waiting for GPU to finish, updating bo_stats tracking).
|
|
The other CMA drivers are using drm_gem_cma_free_object as their
|
|
gem_free_object, so this should be a no-op for them.
