Hi Yingying,

Just curious if these have been submitted to upstream stable as well?

It seems the above fix is dependent on having applied the following
commit.  However, we don't have the following commit applied in
Maverick.  So I assume we want this patch as well? 

commit 0dca94baeab4a1a514841b0a4c8e3a51dfb4d5ae

    hwmon: coretemp: update hotplug condition check

It also appears that it would be beneficial to add the following as
well.  Should this also be considered?

commit 851b29cb3b196cb66452ec964ab5f66c9c9cd1ed
Author: Chen Gong <gong.chen at linux.intel.com>

    hwmon: coretemp: enable coretemp device add operation failure

By adding the additional two patches noted above, this allows for clean
cherry-picks of all the commits with the exception of a4659053 (which is
a simple manual fix up).
