Yes, I agree. Readability of the diffs should be taken into account because
it make the work of reviewers a bit easier.
I'm trying and see if some clean-up of usbctrl_vendorreq() (from which I
copied most of the code and pasted in my new functions) can improve patches
readability if it is carried out preventively (I mean before creating
usb_read() in 2/3 and usb_write() in 3/3).
I hope that that preventive clean-ups would help when in 3/3 I will delete
usbctrl_vendorreq() and the new code overlaps the lines that were used by
that function.
Let's see... Perhaps it may solve out problem :)
Thanks,
