Note that we want to only rip out the encoder->mode_fixup callback.
But we still have the dvo_slave->mode_fixup callback. dvo is gen2
only, so we won't ever touch this again. Hence why I didn't go through
all 6-7 dvo slave drivers and give them the same treatment. I'll add a

This function is called without the dev->struct_mutex held, hence we
need to use the _unlocked unreference variants.

As soon as the object is registered userspace can sneak in here with a
gem_close ioctl call, so the object can (and with my new evil tests
actually does) get the final unreference in this place. The lack of
locking then results in hilarity and some good leakage.

 "These are fixes collected over the last week, they fixes several

  Specifics:

   - the x86_pkg_temp_thermal driver causes crash on systems with no
     package MSR support as there is a bug in the logic to check
     presence of DTHERM and PTS feature together.  Added a change so
     that when there is no PTS support, module doesn't get loaded.

   - fix krealloc() misuse in pkg_temp_thermal_device_add().

     If krealloc() returns NULL, it doesn't free the original.  Thus if
     we want to exit because of the krealloc() failure, we must make
     sure the original one is freed.

   - The error code path of the x86 package temperature thermal driver's
     initialization routine makes an unbalanced call to
     get_online_cpus(), which causes subsequent CPU offline operations,
     and consequently system suspend, to permanently block in
     cpu_hotplug_begin() on systems where get_core_online() returns an

Commit f1a18a10 "Thermal: CPU Package temperature thermal" had code
that did a get_online_cpus(), run a loop and then do a
put_online_cpus(). The problem is that the loop had an error exit that
would skip the put_online_cpus() part.

In the error exit part of the function, it also did a get_online_cpus(),
run a loop and then put_online_cpus(). The only way to get to the error
exit part is with get_online_cpus() already performed. If this error
condition is hit, the system will be prevented from taking CPUs offline.
The process taking the CPU offline will lock up hard.

Removing the get_online_cpus() removes the lockup as the hotplug CPU
refcount is back to zero.

This was bisected with ktest.
