Subject: [usb resume regression] in 3.16-rc1

on resume with 3.16-rc1 I get the following error messages in dmesg
which are alltogether not present in 3.15:

[   43.518116] dpm_run_callback(): 0xffffffffa53c4120 returns -13
[   43.518119] PM: Device 1-1 failed to resume async: error -13
[   43.522380] hub 1-1:1.0: hub_port_status failed (err = -71)
[   43.528538] sd 0:0:0:0: [sda] Starting disk
[   43.530886] hub 1-1:1.0: hub_port_status failed (err = -71)
[   43.535140] usb 1-1-port2: cannot disable (err = -71)
[   43.535142] dpm_run_callback(): 0xffffffffa53c4120 returns -71
[   43.535145] PM: Device 1-1.2 failed to resume async: error -71
[   43.543673] usb 1-1-port4: cannot disable (err = -71)
[   43.543674] dpm_run_callback(): 0xffffffffa53c4120 returns -71
[   43.543679] PM: Device 1-1.4 failed to resume async: error -71

usb devices connected to the hub (in my case mouse and keyboard) are
all death after resume and cannot be activated again.
