Subject: [PATCH] platform/x86: asus-wmi: Ignore return value when writing
 thermal policy

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.

Closes: https://bugzilla.kernel.org/show_bug.cgi?id=219517
Fixes: 2daa86e78c49 ("platform/x86: asus_wmi: Support throttle thermal policy")
