Subject: [PATCH 13/18] HID-debug: Combine 11 seq_printf() calls into one call
 in hid_dump_field()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 7 Feb 2017 20:04:28 +0100

Some data were printed into a sequence by eleven separate function calls.
Print the same data by a single function call instead.
