From 42afa0f8c70e06d6fc2aa09890f29c767c3f0947 Mon Sep 17 00:00:00 2001 From: Jie Deng Date: Thu, 21 Dec 2017 13:32:00 +0800 Subject: net: dwc-xlgmac: Get rid of custom hex_dump_to_buffer() Get rid of 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().
