[PATCH] soc: qcom: socinfo: Open read access to all for debugfs
From: Stephen Boyd
Date: Wed Dec 16 2020 - 02:20:23 EST
There doesn't seem to be any reason to limit this to only root user
readable. Let's make it readable by all so that random programs can
read the debugfs files in here instead of just root. The information is
just that, informational, so this is fine.
