Subject: drm/amdgpu: use ERR_PTR() to return from amdgpu_mn_get
The newly added failure path in amdgpu_mn_get() use the
wrong return type:
drivers/gpu/drm/amd/amdgpu/amdgpu_mn.c: In function 'amdgpu_mn_get':
drivers/gpu/drm/amd/amdgpu/amdgpu_mn.c:237:10: error: return makes pointer from integer without a cast
This adds the necessary ERR_PTR() conversion.
Fixes: ad35eee9fb17 ("drm/amdgpu: make amdgpu_mn_get wait for mmap_sem killable")
