Doing an "allmodconfig" on i386:

The allmodconfig build is still broken upstream.

Thanks,

Hi,

I try to check allmodconfig error issue for aat2870 backlight driver. But I could not observing error message what you attached, building is successed. Please let me know how to reproduce allmodconfig problem for aat2870 backlight driver.

This is my repro step.

$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
$ cd linux-next
$ make allmodconfig
$ make

Thanks,
Jin.

Get Linus' current tree, not linux-next.

Now fixed? current mainline i386 allmodconfig builds OK for me.

Yeah, works ok for me with latest -git as well so something fixed it.
