[PATCH 0/2] Disable automatic load CCS load balancing

[Andi Shyti]

Hi,

I'm sorry, I forgot to add the changelog. Here it is:

v1 -> v2
========
- In Patch 1 use the correct workaround number (thanks Matt).
- In Patch 2 do not add the extra CCS engines to the exposed UABI
  engine list and adapt the engine counting accordingly (thanks
  Tvrtko).
- Reword the commit of Patch 2 (thanks John).
