Revision 09f02902eb9cd41d4b88f4a5b93696297b57a3b0 authored by Heiner Kallweit on 03 March 2024, 10:45:22 UTC, committed by Wolfram Sang on 08 March 2024, 09:10:26 UTC 
i2c: i801: Fix using mux_pdev before it's set
 
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.
