From: Naveen Ch

I've tested with v6 patches and they are working fine on SMDK6410, SMDKC100

and SMDKV210, except for some header inclusion (linux/sched.h) in samsung-
keypad.c.

The build breaking error is like following:

make[3]: *** [drivers/input/keyboard/samsung-keypad.o] Error 1

This error occurs on s5pc100_defconfig having disabled CONFIG_PREEMPT
option. I think sched.h should be included to remove like this
dependency in driver, are there other ways?

I'm not sure root cause is that. But as you said, I think need inclusion it for prevent the problem.
Actually didn't happen it before..so maybe the some core functions have moved between rc-3 and earlier versions...

The sched.h is included by below path.

interrupt.h -> hardirq.h -> smp_lock.h -> sched.h

The smp_lock.h in hardirq.h is included if CONFIG_PREEMPT is defined. 
The samsung keypad driver haven't needed including sched.h before
Dmitry's patch is applied..

Anyway, if no any issues, could you please re-submit updated it soon?

I haven't get yet Dmitry's review of v6 patch set, so i am waiting it.

Thanks.
