No thermal detection on linux 3.15.1-1

[Yamakaky <yamakaky@xxxxxxxxxxxx>]

Hi

I use a MacBook Pro (beggining on 2011), tlp and mbpfan-git.

On 3.14, the fans works OK and tlp-stat -t output something like this :

    --- TLP 0.5 --------------------------------------------

    +++ Temperatures
    Fan speed              =  2001 [/min]
    Temperature     = 50°C

Now, on 3.15, the temperature line in tlp-stat isn't present and the 
fans are at the minimum level (2000/min). It's strange because 
lm_sensors seems to work :

I looked in the kernel changelog, but I can't find anything relevant. 
Any idea ?
