From 0d361b0ac1ad99ecbe401a4eacdeb844dcdf86a2 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Sun, 27 Jun 2021 20:01:50 -0700 Subject: soc: qcom: socinfo: Don't print anything if nothing found Let's skip printing anything if there's nothing to see. This makes it so the file length is 0 instead of 1, for the newline, and helps scripts figure out if there's anything to see in these files.
