Subject: [PATCH 1/4] drm/dp: Use seq_putc() in drm_dp_mst_dump_topology()

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

A few single characters (line breaks) should be put into a sequence.
Thus use the corresponding function "seq_putc".

This issue was detected by using the Coccinelle software.
