From dd0a2d47cfc4c5ffb3e866c94a80c03ff5ecdd70 Mon Sep 17 00:00:00 2001 From: Kaushlendra Kumar Date: Thu, 18 Dec 2025 13:18:33 +0530 Subject: [PATCH] platform/x86: intel/pmt: Replace sprintf() with sysfs_emit() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Replace sprintf() calls with sysfs_emit() in guid_show(), size_show(), and offset_show() sysfs attribute handlers. The sysfs_emit() function provides automatic buffer bounds checking and is the preferred method for formatting sysfs output per Documentation/filesystems/sysfs.rst. This improves safety by preventing potential buffer overflows and aligns with current kernel coding standards for sysfs attribute implementation.
