PHY init failed on Linux 6.8

[cahz]

With the latest develop version (which is required for Linux 6.8), I cannot get our TN9710P (with MV88X3310) to initialize.

Loading the module leads to the following output:

[  878.238757] tn40xx: Tehuti Network Driver from https://github.com/acooks/tn40xx-driver, linux-6.7.y-1

I noticed that the check in tn.c:444 fails. Replacing the condition with !phy_id, it continues a bit further, but later fails:
