From 75faabf6b92ad1d14fce8d45cf40f6db53cf96fd Mon Sep 17 00:00:00 2001 From: Thorsten Blum Date: Tue, 13 Jan 2026 09:21:26 +0100 Subject: [PATCH] thermal: intel: Use sysfs_emit() in a sysfs show function Replace sprintf() with sysfs_emit() in sysfs show functions. sysfs_emit() is preferred to format sysfs output as it provides better bounds checking.
