From caeccd5180930eb8586771bb1935f4f2e456a8e8 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 14 Jul 2016 11:37:29 +0200 Subject: [PATCH] devlink: fix trace format string 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.
