commit 9d6fea5744d6798353f37ac42a8a653a2607ca69 upstream. In case we need to use them for GPU reset prior initializing the asic.

drm/amdgpu/psp: ignore psp response status

2019-01-25T21:15:34Z

In some cases, psp response status is not 0 even there is no problem while the command is submitted. Some version of PSP FW doesn't write 0 to that field. So here we would like to only print a warning instead of an error during psp initialization to avoid breaking hw_init and it doesn't return -EINVAL.
