[PATCH] drm/dp_mst: Simplify character output in drm_dp_mst_dump_topology()

[PATCH] drm/dp_mst: Simplify character output in drm_dp_mst_dump_topology()

Single characters should be put into a sequence.
Thus use the corresponding function “seq_putc” for one selected call.

This issue was transformed by using the Coccinelle software.
