#1638154 — [PATCH 1/4] hamradio: Combine two seq_printf() calls into one in yam_seq_show()

From: Markus Elfring <elfring@users.sourceforge.net>

A bit of data was put into a sequence by two separate function calls.
Print the same data by a single function call instead.

This issue was detected by using the Coccinelle software.

The code was consistently (and probably deliberately) using one seq_printf()
call for each line so that the source looks 'a bit like' the output.

These changes are all stupid.
