This patch series fixes the documentation issues reported by doing
*make htmldocs*, such as:
 - indentation
 - text formatting
 - missing entry on the table of content related to dw-xdata-pcie misc
 driver index

Besides these warnings also fixes some outdated information related to
stop file interface in sysfs.

Changes:
 V2: Added cover-letter
     Added Reported-by, Link, and Fixes tags

You are not doing this for all "misc-devices", you are doing this only
for one specific driver file.

Please look at the example I provided for how to name this and fix up.

Sorry Greg, I didn't see an example provided. Perhaps you forgot it?

I've considered the V1 the 2 patches sent wrongly separately, based on 
your feedback I've generated a v2 to include the cover letter and the 
reported-by, link, and fixes tags.
Was this wrong?

I also placed the change list on the cover letter. Or do you prefer on 
each patch?

No, but you need to say that here, otherwise how do we know this?

Ah, if you put it in the cover letter, that's fine, but I almost never
read them :)

That's right, for some reason I was stuck thinking that was some kind of 
link. My bad.
