From 219daafa8fc27483b2a652d9428d874bf960a6a1 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Tue, 21 Mar 2017 11:20:26 -0700 Subject: google/chromeec: Ensure \_SB.LID0 is present before using it Since we want to support devices that do not have a lid but still use EC, we need to conditionally check if referencing \_SB.LID0 is valid.
