[linux-yocto] [PATCH 06/10] UPSTREAM: backlight: lm3630a_bl: Stop messing with the pwm->period field

[California Sullivan]

From: Boris BREZILLON <boris.brezillon at free-electrons.com>

pwm->period field is not supposed to be changed by PWM users. The only
ones authorized to change it are the PWM core and PWM drivers.
