Subject: [PATCH AUTOSEL for 4.9 020/100] hwmon: (max31790) Set correct PWM value
Date: Wed, 13 Dec 2017 01:56:19 +0000	[thread overview]
Message-ID: <20171213015606.6568-20-alexander.levin@verizon.com> (raw)
In-Reply-To: <20171213015606.6568-1-alexander.levin@verizon.com>

From: Alex Hemme <ahemme@cisco.com>

[ 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")
