Should have put this in the patch message probably, but I wanted to 
point out I have no bad blocks AFAIK on my R6800 (so I can't testify as 
to the functionality). I can confirm the device still works as before 
though.

I'm not sure how eager people are to backport the bad block parser to 
22.03 still at this stage, along with this patch. But it would be neat.

Cheers

Stijn
