Chenyuan Yang found a bunch of syzkall issues:

https://lore.kernel.org/linux-media/PH7PR11MB57688E64ADE4FE82E658D86DA09EA@PH7PR11MB5768.namprd11.prod.outlook.com/

The patches in this series fix the various issues, and with these
in place, it passed the syzkaller tests.

Many thanks to Chenyuan for reporting this and doing all the testing,
since I had a hard timing reproducing them. It took a few months to
track it all down because of that.

Regards,

        Hans
