Compile error in 5.9.0-1 too few arguments to function ‘iio_device_alloc’

[marc-git]

I get the following error log. Is this a naming conflict?

A temporary fix is to comment the line out, that being line 463 in apple-ib-als.c that'll allow you to compile it, not sure what side effects this could have for Mac's with an iBridge/T2/TouchBar, I haven't been able to test that.

This only really and intermediary until someone either PR's a fix or @roadrunner2 makes a fix.

Did you test if it works on macs without the T2 ? I'm interesting in getting the touchbar on my MBP 14,3 working again. Tried the current pull request too but that didn't work (compiled though).

Unfortunately no.

I haven't been able to use the original fork nor roadrunner's they both get the same error messages (dmesg | grep applespi) and it doesn't seem to work even when reloading the module...

Can't for the life of me figure out why...

I got the touchbar back working: https://github.com/roadrunner2/macbook12-spi-driver/issues/42#issuecomment-753445371

I forked it here with rado0x54's fix: https://github.com/PatrickVerner/macbook12-spi-driver

I forked it here with rado0x54's fix: https://github.com/PatrickVerner/macbook12-spi-driver cheers, i'll test on the weekend

[marc-git]

Yes works great for me straight from your fork @PatrickVerner

Sorry not closing because fork is not merged yet
