usb: core: fix potential memory leak in error path during hcd creation
commit 1a744d2eb76aaafb997fda004ae3ae62a1538f85 upstream. Free memory allocated for address0_mutex if allocation of bandwidth_mutex failed. Fixes: feb26ac31a2a ("usb: core: hub: hub_port_init lock controller instead of bus") Signed-off-by: Anton Bondarenko <anton.bondarenko.sama@gmail.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
