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)
