From 3cd6e2f768851a760c072f0f84b9688b1755d24d Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 16 Jul 2015 15:42:14 +0300 Subject: [PATCH] iwlwifi: convert hex_dump_to_buffer() to %*ph There is no need to use hex_dump_to_buffer() in the cases like this: hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false); /* len <= 16 */ sprintf("%s\n", outbuf); since it maybe easily converted to simple: sprintf("%*ph\n", len, buf); Note: it seems in one case the output is groupped by 2 bytes and looks like a typo. Thus, patch changes that to plain byte stream.
