Turned on that driver->owner which is struct module is not available when
modules are disabled. Better to depend on a driver name which is
always available.

From: Arnd Bergmann <arnd@arndb.de>

Including devlink.h on ARM and probably other 32-bit architectures results in
a harmless warning:

In file included from ../include/trace/define_trace.h:95:0,
                 from ../include/trace/events/devlink.h:51,
                 from ../net/core/devlink.c:30:

include/trace/events/devlink.h:42:12: error: format '%lu' expects argument of type 'long unsigned int', but argument 10 has type 'size_t {aka unsigned int}' [-Werror=format=]

The correct format string for 'size_t' is %zu, not %lu, this works on all
architectures.
