[PATCH] drm/amdgpu/pm: fix powerplay OD interface
Alex Deucher
alexander.deucher at amd.com
Tue Nov 23 20:01:13 UTC 2021
The overclocking interface currently appends data to a
string. Revert back to using sprintf().
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1774
Fixes: 6db0c87a0a8ee1 ("amdgpu/pm: Replace hwmgr smu usage of sprintf with sysfs_emit")
