If anyone has any objections, please let me know. ------------------ From: Mathias Nyman commit f3dc41c5d22b2ca14a0802a65d8cdc33a3882d4e upstream. usb_hc_died() should only be called once, and with the primary HCD as parameter. It will mark both primary and secondary hcd's dead. Remove the extra call to usb_cd_died with the shared hcd as parameter.
