Subject: [PATCH v2] i2c: Convert to using %pOFn instead of device_node.name
Date: Fri, 28 Sep 2018 17:49:47 -0500 [thread overview]
Message-ID: <20180928224947.19058-1-robh@kernel.org> (raw)
In preparation to remove the node name pointer from struct device_node,
convert printf users to use the %pOFn format specifier.
