S3C24XX_ADC should be added to the depends.

I think this is not really needed because kernel.h is included already.

Well, we take 2410_ts as s3c adc client, so these work has been done in
s3c_adc_probe function of arch/arm/plat-s3c24xx.c
This should be duplicated.
And "#include <linux/clk.h>" is not needed because we don't use these
APIs

Above reason and also for those "goto err_clk;"

Same as above
