Re: aat2870 causes build failure in current upstream

[Jinyoung Park]

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.
