RE: [PATCH V2 02/17] drm/amd/pm: do not expose power implementation details to amdgpu_pm.c

["Chen, Guchun" <Guchun.Chen@amd.com>]

[Public]

Two nit-picks.

1. It's better to drop "return" in amdgpu_dpm_get_current_power_state.

2. In some functions, when function pointer is NULL, sometimes it returns 0, while in other cases, it returns -EOPNOTSUPP. Is there any cause for this?

Regards,
Guchun

Subject: [PATCH V2 02/17] drm/amd/pm: do not expose power implementation details to amdgpu_pm.c

amdgpu_pm.c holds all the user sysfs/hwmon interfaces. It's another
client of our power APIs. It's not proper to spike into power
implementation details there.
