Subject: mcb:[PATCH] use sysfs_emit_at() instead of scnprintf() in show functions
Date: Thu,  3 Jul 2025 16:02:42 +0530	[thread overview]
Message-ID: <20250703103241.10199-1-abhinav.ogl@gmail.com> (raw)


This change improves clarity and ensures proper bounds checking in
line with the preferred sysfs_emit() API usage for sysfs 'show'
functions. The PAGE_SIZE check is now handled internally by the helper.

No functional change intended.
