From 43a49f8baa6b0e7e5b68ed0ee141e1efacfd9ae6 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 17 Jun 2007 19:50:51 +0200 Subject: PM: Do not check parent state in suspend and resume core code The checks if the device's parent is in the right state done in drivers/base/power/suspend.c and drivers/base/power/resume.c serve no particular purpose, since if the parent is in a wrong power state, the device's suspend or resume callbacks are supposed to return an error anyway. Moreover, they are also useless from the sanity checking point of view, because they rely on the code being checked to set dev->parent->power.power_state.event appropriately, which need not happen if that code is buggy. For these reasons they can be removed. Signed-off-by: Rafael J.
