Like I said in [1], this is a big scary patch that has been reported to
break DSI VDSC. I tried to skim through it, but it's really impossible
to identify the one thing that could break DSI.

I mean, even if you had the hardware to test, it could take days to
identify the regressing part here.

And this isn't really specific to DSI, but rather to *any* regression
this might cause. Afterwards, would you stand a chance of telling what
goes wrong if you get a bisect result?


BR,
Jani.
