    drm/amdkfd: fix svm_migrate_fini warning · 197ae177
    Philip Yang authored
    Device manager releases device-specific resources when a driver
    disconnects from a device, devm_memunmap_pages and
    devm_release_mem_region calls in svm_migrate_fini are redundant.
    
    It causes below warning trace after patch "drm/amdgpu: Split
    amdgpu_device_fini into early and late", so remove function
    svm_migrate_fini.
