From 9a07ae68932b81c5666035aec3f7cb3017e5b13e Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 19 Dec 2017 23:22:15 +0200 Subject: [PATCH] net: amd-xgbe: Get rid of custom hex_dump_to_buffer() Get rid of yet another custom hex_dump_to_buffer(). The output is slightly changed, i.e. each byte followed by white space. Note, we don't use print_hex_dump() here since the original code uses nedev_dbg().
