It has to do, in a certain sense. Let me explain please... Some days ago, David Laight made the review of "Shorten calls chain of rtw_write8/16/32/n()" version 3. In that patch he noticed some lines of usb_read() that I had created with the help of reusing some lines of the code of usbctrl_vendorreq() that is deleted in the same patch. He thought that they were clean-ups and renames and so he suggested to make those "clean-ups" in a separate patch. However they were _not_ renames or other clean-ups, because usb_read() was not touched in that patch and, above all, it was a new function. I am sure that when I write new functions I can use whatever name of variables I like, even if people may think I'm renaming the variables that were in a old function that now is deleted. Am I not permitted? However, because I also think that readability of the diffs matters, I decided to do some clean-up of the code I'm about to reuse in the new functions. It improves readability of the above-mentioned patch that is also the 18/18 of this series. That is the reason why I'm cleaning up a function that is going to be deleted in the last patch of the series. > Don't use a link like that in the commit message especially when it's a > link to an email you wrote.

That way you give credit to the other person but all the > information is in the commit message. I agree with you. I'll redo the commit message for in order to summarize in few lines why I'm doing clean-ups of functions that must be deleted in 18/18. The same for 16/18. I think that a short explanation like the one that I gave you above should suffice (much shorter, obviously). I hope that I've been clear now. Please let me know if you have more suggestions about this patch and the next (16/18). Regards, Fabio
