Sumeet has a patch to fix the same issue, which has been in my tree
https://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux.git/commit
/?h=next&id=1948d498dcf680bc650391f23da2f97e59f9126d

Plus, the previous fix is wrong because proc_dev will be left
uninitialized if proc_thermal_emum_mode equals PROC_THERMAL_PCI.

thanks,

oh, Sumeet's patch is the right one and much cleaner.
