Subject: thermal: intel: int340x: Add new line for UUID display
From: Srinivas Pandruvada <srinivas.pandruvada@xxxxxxxxxxxxxxx>
commit 5f7fdb0f255756b594cc45c2c08b0140bc4a1761 upstream.
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.
