Why the "dcft_" prefix?  We know this is a "dvi control device" by the
fact that the type says it is :)

"pfn_" means "pointer to a function" which is not needed at all.  Just
make this be "init".

And the whole crazy "PFN_DVICTRL_INIT" also is not needed, just put the
real function prototype in here so that we don't have to unwind the mess
to look it up.

So, this line would look like:
	void (*init)(void);

Much smaller, more obvious, matches the kernel coding style, and is way
easier to understand exactly what is happening here.

Typedefs can be used to hide complexity, but here they are just adding
it, for no good reason at all.

I appreciate long patch series being sent out, but maybe make them
smaller so you do not have to redo 49 patches because you are asked to
make a change on the very first patch like here.  Perhaps stick to 20
max for a bit until you get the process down and understand more about
what the kernel programming style is?

thanks,

Didn't catch that--makes sense.

I changed that in one of the next few patches, but now I realize I should have
combined the two changes.

Sounds good. Thank you for the feedback. I will work more on this.
