Hi Tianci,
My point is, as in the new patch, one new local adev variable is introduced,
then in the same function, for others where smu->adev is used should be replace
by the new local adev as well.
Otherwise, it looks not perfect from coding style's perspective.
Regards,
Guchun

Hi Guchun,
Since the adev variable invoked a few times, local adev make the code more
concise.
Thanks!

after GFXOFF exit
From: "Tianci.Yin" <tianci....@amd.com>
On Navi1x, the SPM golden settings will be lost after GFXOFF enter/exit,
reconfigure the golden settings after GFXOFF exit.
