Hi Linus,
Looks like ff2b13592299 ("gpio: make the gpiochip a real device")
broke booting on all omaps, and probably other machines too according
to this:
https://kernelci.org/boot/all/job/next/kernel/next-20160217/
So far we've gone from 1 failed machine with next-20160216 to
18 failed machines with next-20160217.
The error I'm getting on omaps is below with debug_ll enable,
any ideas?
Regards,
Tony
