You can from now on.

I didn't remember which commit was it so I didn't include it in the patch
description. This is certainly not the commit above (if you're making such,
changes please make sure that you actually understand the code -- you have
it easy now as it is orders of magnitude simpler than it was few years ago).
Looking a bit more in depth it could be that it was never a regression
and I'm no longer sure that the change is correct (sorry for that, I was
blinded by code in pata_cs5520.c).
