4.19-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 35fdc3902179366489a12cae4cb3ccc3b95f0afe ]
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.
