One problem caused by that is increasing the time of system suspend if there are many runtime-suspended devices to resume during it (because the .prepare() callbacks are executed sequentially). The following two patches are intended to improve that one aspect slightly in those two subsystems. Thanks! -- I speak only for myself. Rafael J.
