Nope.  That'd be your own preferred style.

If you want it to be followed by others,
please try and get it added to CodingStyle
and use examples to show why it's better
than allowing maintainer preference.

My own preferred style here would be to align
the display->regwidth and display->buswidth so
I can differentiate the similarity in naming a
bit more easily.

	} else if (display->regwidth == 8 &&
		   display->buswidth == 9 && par->spi) {

I'm not sure at all there is a single best
style for this and it can easily become
situation dependent.

And so I suggest not adding anything about this
style nit to CodingStyle.
