[PATCH v1 4/5] parisc: use seq_hex_dump() to dump buffers

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
Date: 2014-07-09 15:24:29
Also in: linux-fsdevel, linux-media, linux-s390, lkml
Subsystem: parisc architecture, the rest · Maintainers: "James E.J. Bottomley", Helge Deller, Linus Torvalds

Instead of custom approach let's use recently introduced seq_hex_dump() helper.
