dmesg kernel 4.4

On my machine with an:

  Model: "nVidia Quadro FX 1500"
  Vendor: pci 0x10de "nVidia Corporation"
  Device: pci 0x029e "Quadro FX 1500"
  SubVendor: pci 0x10de "nVidia Corporation"
  SubDevice: pci 0x032c 
  Revision: 0xa1
  Driver: "nouveau"
  Driver Modules: "drm"

graphics card, the gpu fan start running at high load.
The issue started after installing openSUSE Leap15 with kernel version 4.12.
The same issue is visible using kernel version 4.17.
It was working fine on older openSUSE versions, up to kernel version 4.4.
Installing kernel version 4.4 on Leap 15 makes the issue go away.
The nouveau driver debug logs show when booting with kernel 4.12:

We confirmed that the commit below brought the regression:
commit 800efb4c2857ec543fdc33585bbcb1fd5ef28337
    drm/nouveau/drm/therm/fan: add a fallback if no fan control is specified in
the vbios

Reverting the commit fixes the problem on Thomas' machine.

Takashi Iwai, thanks a lot for finding a solution for that!
I am having this issue since over a year and nothing happens. I am willing to
switch over to suse when this would finally get fixed and the GPU card wont
spin at 100% the whole time.
Here one of mine bugreports:

I *guess* that a more better fix would be to check the error from the fan-table
parsing and avoid the linear fallback when it failed, instead of the whole
revert.

--- Comment #5 from Takashi Iwai <tiwai-l3A5Bk7waGM@public.gmane.org> ---
One problem seems to be that the thermal target is set only once by the linear
fallback, and forgotten.  The patch below "fixes" that, at least, to keep
updating the fan with the linear fallback.

But, according to Thomas, this still seems too high.  I'm not sure whether it's
the correct behavior or it was just because the fan never worked in the past.
