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. Wysocki <rjw@sisk.pl> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
