Subject: Re: [PATCH v2 3/4] drm/amd/display: Remove parameters from
rq_dlg_get_dlg_reg

First of all, thanks a lot for this patch. This change is really helpful
for reducing the stack size. I just have few comments inline.

hmmm... I'm not sure if I missed something, but you dropped the variable
pstate_en from the parameter list, but you still have it here. Is this
correct?

Why are we dropping these logs? It is already hard to debug DML code,
and reducing the amount of information that we can get does not sound
good to me.
