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
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.

* only have about 140 entries, but mips and parisc have more sparsely
* allocated errnos (with EHWPOISON = 257 on parisc, and EDQUOT = 1133
* on mips), so this wastes a bit of space on those - though we
* special case the EDQUOT case.
