Subject: [PATCH 5/6] driver core: make driver_detach() take a const *

driver_detach() does not modify the driver itself, so make the pointer
constant.  In doing so, the function driver_allows_async_probing() also
needs to be changed so that the pointer type passes through to that
function properly.
