[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

[PATCH v2 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, v2.
Changes since v1:
- Replace patch [1/7] to use pci_save_state() / pci_restore_state()
for consistency between runtime PM code path of bound and unbound
devices. (Rafael, Bjorn)
- Patch [5/7]: Drop an unnecessary initialization. (Bjorn)
