[PATCH 0/7] Modernize vga_switcheroo by using device link for HDA
Modernize vga_switcheroo by using a "device link" to enforce a runtime PM
dependency from an HDA controller to the GPU it's integrated into.
Remove thereby obsoleted code and fix a bunch of bugs.
Device links were introduced in v4.10.
Users might see a small power saving if the discrete GPU is in use and
its HDA controller is not, because the HDA controller is now allowed
to runtime
