Do you mean "look at the function below", using "below" as an adverb?
"below" is not an adjective.

If you take a look at the below function, you should not use driver's release
to free adev. As dev is embedded in adev.

Use the implicit kref infrastructure to free the container
struct amdgpu_device, container of struct drm_device.
First, in drm_dev_register(), do not indiscriminately warn
when a DRM driver hasn't opted for managed.final_kfree,
but instead check if the driver has provided its own
"release"
The amdgpu driver implements its own DRM driver
release function which naturally frees
the container struct amdgpu_device of
the DRM device, on a "final" kref-put,
i.e. when the kref transitions from non-zero

Drivers usually allocate their container

which initializes the contained DRM dev kref to 1.
A DRM driver may provide their own kref
release method, which frees the container

The correct thing to do this is to

remove "drmm_add_final_kfree()" and qualify

the existence of drm_driver.release() (i.e. non-NULL).

Hi, Felix,
If GPU hang, execute_queues_cpsch will fail to unmap or map queues and
then create_queue_cpsch will return error. If pqm_create_queue find
create_queue_cpsch failed, it will call uninit_queue to free queue object.

I'm not sure how the bug you're fixing is caused, but your fix is
clearly in the wrong place.
A queue being disabled is not the same thing as a queue being destroyed.
Queues can be disabled for legitimate reasons, but they still should
exist and be in the qpd->queues_list.
