amdkfd (part of amdgpu) driver supports the AMD GPU compute stack. amdkfd exposes only a single device /dev/kfd even if multiple AMD GPU (compute) devices exist in a system. However, amdgpu drvier exposes a separate render device file /dev/dri/renderDN for each device. To participate in device cgroup amdkfd driver will rely on these redner device files. v2: Exporting devcgroup_check_permission() instead of __devcgroup_check_permission() as per review comments.
