From f807e8be46991a5a58774a4d6344359b01c949e8 Mon Sep 17 00:00:00 2001 From: Chris Packham Date: Wed, 17 Mar 2021 17:02:30 +1300 Subject: hwmon: (pmbus) Replace - with _ in device names before registration The hwmon sysfs ABI requires that the `name` property doesn't include any dashes. But when the pmbus code picks the name up from the device tree it quite often does. Replace '-' with '_' before registering the device.
