Nice.  Yes, that fixes it, thanks!

I checked the commit diff for any similar potential errors.  Most of the
changes are "obviously correct".  However, there are changes in
thermal.c which look similar to the one that caused the problem in the
EC driver.

I think someone knowledgeable needs to audit the changes to the thermal
driver, in case the Thinkpads start melting again :-P.  The commit#
again: 27663c5855b10af9ec67bc7dfba001426ba21222.
