Subject: [PATCH v4] coresight: Replace scnprintf() with sysfs_emit() in sysfs show functions
Documentation/filesystems/sysfs.rst mentions that show() should only
use sysfs_emit() or sysfs_emit_at() when formating the value to be
returned to user space. So replace scnprintf() with sysfs_emit().
Signed-off-by: Chelsy Ratnawat <chelsyratnawat2001@...il.com>
---
Changes in v4:
- Applied changes to 5 more files to replace sprintf/scnprintf with
sysfs_emit() and sysfs_emit_at()
- No functional changes intended
