Regards Seb >From 05aa55dddb9ee4045c320661068bea78dad6a6e5 Mon Sep 17 00:00:00 2001 From: Ohad Ben-Cohen <[email protected]> Date: Thu, 9 Sep 2010 00:46:16 +0200 Subject: [PATCH] PM / Runtime: Lenient generic runtime pm callbacks Allow drivers, that belong to subsystems which use the generic runtime pm callbacks, not to define runtime pm suspend/resume handlers, by implicitly assuming success in such cases. This is needed to eliminate nop handlers that would otherwise be necessary by drivers which enable runtime pm, but don't need to do anything when their devices are runtime-suspended/resumed.
