Subject: i2c: i801: Fix using mux_pdev before it's set
From: Heiner Kallweit <hkallweit1@xxxxxxxxx>
commit 09f02902eb9cd41d4b88f4a5b93696297b57a3b0 upstream.
i801_probe_optional_slaves() is called before i801_add_mux().
This results in mux_pdev being checked before it's set by
i801_add_mux(). Fix this by changing the order of the calls.
I consider this safe as I see no dependencies.
