4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wang Nan <wangnan0@huawei.com>
commit f2c8852e6e990fcab0d9e68de9d86e5fbea0b5dc upstream.
On ARM32 building it report following error when we build with libbabeltrace:
util/data-convert-bt.c: In function 'add_bpf_output_values': util/data-convert-bt.c:440:3: error: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'unsigned int' [-Werror=format] cc1: all warnings being treated as errors
Fix it by changing %lu to %zu.
