Hello Olof,
I compiled the latest git kernel 2 days ago. The kernel boots and works
but unfortunately I get the following error messages about the
i2c-pasemi during the start:
[ 3.553461] i2c /dev entries driver

[ 3.555161] i2c-pasemi: probe of 0000:00:1c.2 failed with error -16
The commit "Merge branch 'i2c/for-4.8'" is the problem. Link:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=66304207cd341045df34195b4a8d422075bff513
I reverted the i2c commit with:
git revert 66304207cd341045df34195b4a8d422075bff513 -m 1
After that I was able to compile it. It boots without the error messages
about the i2c-pasemi.
Do we need to modify the "i2c-pasemi.c"?
Cheers,
Christian
