Eric, does the problem still happen with latest mainline was this issue addressed meanwhile?

Hi Thorsten, yes, it appears the problem is still there in the latest mainline. I had sent an email to the owner of the driver about the fix I had done locally, in order to get some feedback since I'm not an expert on the driver. However, never received any response. I'm going to go ahead and just file a patch later today with the fix that I did locally.

Patch submitted and accepted. Fixed as noted in description, i.e. add NULL check for desc pointer.
