So is there any particular reason why this wasn't applied?Let me remind Artem by resending the patch tomorrow.Actually ... the SPI does have the heuristics to probe this chip without the patch. But there was this discussion about them eventually being removed. That was a point raised by you I think. Is that still valid?That was a point raised by Grant. IIRC, the reason I made the patch is my system does not probe the device without the patch. I can retest, and if it's true that the patch is not necessarily needed, I will probably let it be.

I use this + my SPI patches I submitted recently.
