[PATCH AUTOSEL for 4.9 020/100] hwmon: (max31790) Set correct PWM value

[alexander . levin]

From: Alex Hemme <ahemme@xxxxxxxxx>

[ Upstream commit dd7406dd334a98ada3ff5371847a3eeb4ba16313 ]

Traced fans not spinning to incorrect PWM value being written.
The passed in value was written instead of the calulated value.

Fixes: 54187ff9d766 ("hwmon: (max31790) Convert to use new hwmon registration API")
