In that case, since the new device (the child) is added\nto dpm_active after its parent, the PM core will attempt to\nsuspend it after the parent, which is wrong.\n\nIntroduce a new member of struct dev_pm_info, called \u0027sleeping\u0027,\nand use it to check if the parent of the device being added to\ndpm_active has been suspended, in which case the device registration\nfails. Also, use \u0027sleeping\u0027 for checking if the ordering of devices\non dpm_active is correct.\n\nIntroduce variable \u0027all_sleeping\u0027 that will be set to \u0027true\u0027 once all\ndevices have been suspended and make new device registrations fail\nuntil \u0027all_sleeping\u0027 is reset to \u0027false\u0027, in order to avoid having\nunsuspended devices around while the system is going into a sleep state.\n\nRemove pm_sleep_rwsem which is not necessary any more.\n\nSpecial thanks to Alan Stern for discussions and suggestions that\nlead to the creation of this patch.\n\nSigned-off-by: Rafael J.
