From 5f7fdb0f255756b594cc45c2c08b0140bc4a1761 Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Mon, 22 May 2023 15:38:44 -0700 Subject: [PATCH] thermal: intel: int340x: Add new line for UUID display Prior to the commit "763bd29fd3d1 ("thermal: int340x_thermal: Use sysfs_emit_at() instead of scnprintf()", there was a new line after each UUID string. With the newline removed, existing user space like "thermald" fails to compare each supported UUID as it is using getline() to read UUID and apply correct thermal table. To avoid breaking existing user space, add newline after each UUID string.
