Subject: [PATCH/RESEND] soc: qcom: socinfo: Don't print anything if nothing found
Date: Sun, 27 Jun 2021 20:01:50 -0700	[thread overview]
Message-ID: <20210628030150.2627905-1-swboyd@chromium.org> (raw)

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.
