[PATCH] locking/lockdep: Use seq_putc() in five functions

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sun, 14 Jul 2024 12:18:16 +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.
