Doesn't "runtime suspend" mean an individual device is suspended while the rest of the system remains active? If so, maybe it would be more direct to say "PCI devices not bound to a driver cannot be runtime

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) Rephrase
