Subject: [PATCH 2/4] video/backlight-pwm: fix the value of 'brightness_max'.
Date: Thu, 14 Jul 2016 16:17:16 +0200 [thread overview]
Message-ID: <20160714141718.20121-3-iw3gtf@arcor.de> (raw)
In-Reply-To: <20160714141718.20121-1-iw3gtf@arcor.de>
In-Reply-To: <20160713051805.GZ20657@pengutronix.de>
The field pwm_backlight->backlight.brightness_max should be the maximum
allowed brightness value for the backlight, not the max index of the
array 'pwm_backlight->levels[]'.
