| Subject: hwmon: (max31790) Set correct PWM value |
| |
| 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") |
