Subject: [PATCH] drm/amdgpu: Use seq_putc() in two functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 12 Jan 2018 22:08:50 +0100

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

This issue was detected by using the Coccinelle software.
