In upstream we have a preference that there's some kind of limit for
loops, to avoid neverending loops.

I wish you had split the patches per file like I asked, it makes
reviewing a new driver so much easier. Reviewing is hard, please always
take us reviewers into consideration when submitting patches.
No need to resend because of this, but I am grumpy.

Hi Kalle,
I am sorry for any inconvenience caused.
Will keep this in mind when upstreaming a new driver next time.
