Subject: [PATCH] dmaengine: Use seq_putc() in two functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 13 Jul 2024 12:30:30 +0200

Single characters (line breaks) should be put into a sequence.
Thus use the corresponding function “seq_putc”.

This issue was transformed by using the Coccinelle software.
