[PATCH v1 2/2] pwm: bcm-iproc: remove unnecessary check of 'duty'

From: Rayagonda Kokatanur
Date: Mon Mar 23 2020 - 02:53:48 EST


Variable 'duty' is u32. Hence the less-than zero
comparison is never true, remove the check.

Fixes: daa5abc41c80 ("pwm: Add support for Broadcom iProc PWM controller")
