[PATCH v2 1/2] tracing/user_events: Use seq_putc() in two functions

From: Markus Elfring <[email protected]>
Date: Mon, 22 Jun 2026 16:37:18 +0200

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

The source code was transformed by using the Coccinelle software.
