Subject: [PATCH] i2c: Convert to using %pOF instead of full_name

From: Rob Herring <[email-masked]>
Date: Tue, 18 Jul 2017 16:43:06 -0500

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.
