[PATCH/RESEND] soc: qcom: socinfo: Don't print anything if nothing found

From: Stephen Boyd
Date: Sun Jun 27 2021 - 23:01:56 EST


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.
