6.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Armin Wolf <W_Armin@xxxxxx> [ Upstream commit 25fb5f47f34d90aceda2c47a4230315536e97fa8 ] On some machines like the ASUS Vivobook S14 writing the thermal policy returns the currently writen thermal policy instead of an error code. Ignore the return code to avoid falsely returning an error when the thermal policy was written successfully.
