From f7a652182cc7f07cf658b8eee8d545ac109fd02e Mon Sep 17 00:00:00 2001 From: Eddie James Date: Tue, 22 Dec 2020 09:26:40 -0600 Subject: [PATCH] hwmon: (pmbus/ibm-cffps) Set the PMBUS_NO_CAPABILITY flag Several power supplies supported by the IBM CFFPS driver don't report valid data in the CAPABILITY register. This results in PEC being enabled when it's not supported by the device, and since the automatic version detection might fail, disable use of the CAPABILITY register across the board for this driver.
