We changed the API here a couple months ago. It suspend() only takes
one argument now. GCC complains about this:
drivers/usb/host/bcma-hcd.c:320:2: warning: initialization from
incompatible pointer type [enabled by default]
drivers/usb/host/bcma-hcd.c:320:2: warning: (near initialization
for ‘bcma_hcd_driver.suspend’) [enabled by default]
