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: In function 'trace_raw_output_devlink_hwmsg':
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.
