This can reduce system suspend/resume time about 20ms, from 1030ms to 1010ms on ASUS T100TA machine. Although the improvement is not very significant, but this can let your parent/child device suspend/resume more asynchronously and take advantage of multicore to improve overall system suspend/resume speed.
I have resent this patch with updated commit message - "[PATCH v2] hid: enable hid device to suspend/resume asynchronously".
Thanks, Zhonghui
