From b2be2422c0c98b00f21c4331e2d9342bd58bfdba Mon Sep 17 00:00:00 2001 From: Vadim Pasternak Date: Sun, 26 Sep 2021 08:35:41 +0300 Subject: hwmon: (mlxreg-fan) Support distinctive names per different cooling devices Provide different names for cooling devices registration to allow binding each cooling devices to relevant thermal zone. Thus, specific cooling device can be associated with related thermal sensor by setting thermal cooling device type for example to "mlxreg_fan2" and passing this type to thermal_zone_bind_cooling_device() through 'cdev->type'.
