From 35fdc3902179366489a12cae4cb3ccc3b95f0afe Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Sun, 11 Nov 2018 13:01:11 +0100 Subject: hwmon: (raspberrypi) Fix initial notify MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In case an under-voltage happens before probing the driver wont write the critical warning into the kernel log. So don't init of last_throttled during probe and fix this issue.
