Currently, there are a couple of problems in thermal core framework after boot
and resume from system sleep state, because the thermal zone devices are not
put into a proper state in these cases.

Details of the problems are described in the patch change logs.

which is shipped in 3.18.

Bug 91411 needs patch 1/3, 2/3 to fix, while 92431 needs all three patches.

If possible, I'd like to push these patches into 4.0-rc and 3.18/3.19 stable
kernel as it actually fixes a regression in 3.18.

Any comments are welcome.

thanks,
rui
