Subject: [PATCH] sched: Use seq_putc() in four functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 14 Jul 2024 14:25:33 +0200

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

This issue was transformed by using the Coccinelle software.
