Subject: [PATCH RFC v2 16/32] dsa: mv88e6xxx: Use bus in mv88e6xxx_lookup_name()
Date: Sun, 28 Feb 2016 17:41:24 +0100	[thread overview]
Message-ID: <1456677700-23027-17-git-send-email-andrew@lunn.ch> (raw)
In-Reply-To: <1456677700-23027-1-git-send-email-andrew@lunn.ch>

mv88e6xxx_lookup_name() returns the model name of a switch at a given
address on an MII bus. Using mii_bus to identify the bus rather than
the host device is more logical, so change the parameter.

Signed-off-by: Andrew Lunn <andrew@lunn.ch>
---
v2: Check bus is valid before dereferencing it.
