The bug is “status: NEEDINFO”, so I assume it’s not fixed yet.  In the meantime, manually loading the windfarm modules is a tested workaround.

Does this workaround work for you, too?

"However, there is a workaround: In addition to CONFIG_I2C_POWERMAC=y you
need to compile "Device Drivers → Macintosh device drivers → WINDFARM=y"
statically into the kernel. Then, the relevant WINDFARM_xx module gets
automatically loaded again."


Merely a follow up.

I have tested this and run the change :

    therm_windtunnel: drop using attach_adapter

git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/macintosh?id=3e7bed52719de4b5b5fb900869e293eae0bc3f3e

For weeks now with no issues.

I am switching to 4.18.9 now and the drivers/macintosh/therm_windtunnel.c file therein is still original. I see no reason why
the change could not be pushed into the linux kernel proper.
