ad4e22fa47 ARM: S3C: move s3c_adc_remove to .devexit.text
The function s3c_adc_remove is used only wrapped by __devexit_p so define
it using __devexit.

d43c36dc6b headers: remove sched.h from interrupt.h
After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!
Many thanks to Heiko Carstens for allowing this.

e170adcb40 ARM: S3C: Add ADC synchronous read call.
To add HWMON support, we need a synchronous read() call that blocks
until completion. Add the client that is being service to the select
and convert callbacks to make the code easier.

3f7ea467be [ARM] S3C: ADC: Expose number of remaining conversions to
convert callback

This patch allow us to efficiently modify the number of
remaining conversions from the client side. This us useful
when we do not know in advance how many conversions we will
need or when we need to cancel pending conversions.

This change is simple enough to be compatible with existing
code that can just define the new pointer in the callback
and ignore it.

Sample usage:

f8c8ac8109 [ARM] S3C: Fix ADC driver sparse warning
The symbol 's3c_adc_try' in arch/arm/plat-s3c24xx/adc.c
does not need to be exported and thus should be static.

This fixes the following sparse warning:

adc.c:103:6: warning: symbol 's3c_adc_try' was not declared. Should it be static?
