Thanks for your review.
It was wrong for me to create s3c24xx-pwm platform device as it is
already created in samsung_bl_set(). Hence I would be dropping that.
However, dropping .0 from provider name results in following. (as the
device name is s3c24xx-pwm.N).
[ 0.240000] pwm-backlight pwm-backlight.0: unable to request PWM,
trying legacy API
I will resubmit the patch with these changes.
