| Subject: drm/amdgpu: Avoid leaking PM domain on driver unbind (v2) |
| |
| From: Alex Deucher <alexander.deucher@amd.com> |
| |
| commit 458d876eb869d5a88b53074c6c271b8b9adc0f07 upstream. |
| |
| We only support vga_switcheroo and runtime pm on PX/HG systems |
| so forcing runpm to 1 doesn't do anything useful anyway. |
| |
| Only call vga_switcheroo_init_domain_pm_ops() for PX/HG so |
| that the cleanup path is correct as well. This mirrors what |
| radeon does as well. |
| |
| v2: rework the patch originally sent by Lukas (Alex) |
