| Summary | [REGRESSION] navi10: writing to pp_table fails (5.4-rc6 = working) |

dmesg log (journalctl -k) for the failure.
On 5.4-rc6, with navi10, writing to the sysfs pp_table works, with the SMU
resetting successfully.
On amd-staging-drm-next (270209307880ec946cfe9b98a6a58d285dbc5a2e), this fails.
I can bisect, but unfortunately I'm not too sure on where to start, since the
amd-staging-drm-next branch is currently rebased off of an older version
(5.3-rcX I think?). Tips on where to start would be helpful and appreciated,
but my guess that this would be introduced in the big refactor to remove the
swSMU code layer.
