[PATCH v5 3/6] parisc: use seq_hex_dump() to dump buffers

From: Andy Shevchenko
Date: Tue Jul 07 2015 - 13:06:12 EST


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

In one case it changes the output from
1111111122222222333333334444444455555555666666667777777788888888
to
11111111 22222222 33333333 44444444 55555555 66666666 77777777 88888888

though it seems it prints same data (by meaning) in both cases. I decide to
choose to use the space divided one.
