[PATCH v1 1/2] drm/amdgpu: remove unnecessary save/restore of pdev->d3_delay

From: Bjorn Helgaas
Date: Mon Jan 30 2017 - 15:41:06 EST


Remove unnecessary save/restore of pdev->d3_delay.

The only assignments to pdev->d3_delay are in radeon_switcheroo_set_state()
and some quirks, none of which should be relevant in the
amdgpu_switcheroo_set_state() path.
