From ff448bbaacfb6f216ae101c1f16d8c5142c16fdf Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 18 Nov 2021 12:41:50 +0100 Subject: platform/x86: think-lmi: Simplify tlmi_analyze() error handling a bit Creating the tlmi_pwd_setting structs can only fail with -ENOMEM, set ret to this once and simplify the error handling a bit.
