[PATCH 3.8-stable] thermal: return an error on failure to register thermal

[PATCH 3.8-stable] thermal: return an error on failure to register thermal

[Jonghwan Choi]

3.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Richard Guy Briggs <rbriggs@redhat.com>"

commit da28d966f6aa942ae836d09729f76a1647932309 upstream.

The return code from the registration of the thermal class is used to
unallocate resources, but this failure isn't passed back to the caller of
thermal_init.  Return this failure back to the caller.

This bug was introduced in changeset 4cb18728 which overwrote the return
code
when the variable was re-used to catch the return code of the registration
of
the genetlink thermal socket family.

I believe this is applicable to all the other stable kernels.

Ok, I object, given that I told you to change the format of the message
you send out.  Please look at how others on the stable@ mailing list
send "should this patch be applied" messages, and copy how that is done.

You linewrapped the patch message, careful, you might mess up the patch
itself as well :(

You aren't signing off on it as well?  Why not?
