-Subject: PCI/PM: Add needs_resume flag to avoid suspend complete optimization
-
-From: Imre Deak <imre.deak@intel.com>
-
-commit 4d071c3238987325b9e50e33051a40d1cce311cc upstream.
-
-Some drivers - like i915 - may not support the system suspend direct
-complete optimization due to differences in their runtime and system
-suspend sequence. Add a flag that when set resumes the device before
-calling the driver's system suspend handlers which effectively disables
-the optimization.
-
-Needed by a future patch fixing suspend/resume on i915.
-
-Suggested by Rafael.
