Correct two minor issues in the GSO programmer's guide:
- a note is rendered incorrectly in the middle of an unordered list;
  this results in the remainder of the list appearing inside the note.
  Move note to end of the list to resolve same.
- two minor visual artifacts are present in the 'three-part-output-segment'
  diagram. Remove same.

Fixes: f6010c7 ("doc: add GSO programmer's guide")

Hi Mark,

The _note target should be more specific since the these targets are used
across all the documentation. So something like _gso_note would be better.
Or alternatively leave out the target and just say something in the text
like "See the note below.", without the link, since the note is quite close
to the referring text.

Also, the note isn't indented to the level of the bullet point. I don't know
if that is intentional or not but I would say there should be an additional
3 spaces indentation from ..note:: to the end of the note.

With or without these changes:

Hey John,

Thanks for the feedback - responses inline.

I'll post v2 now, and carry forward your Ack.

Cheers,

I've moved the note back to its original position, but corrected the indentation, so this target can be removed.

As above (the syntax highlighting of my editor shows indented 'note' tags as incorrect, which is why indentation was incorrect in the first place!).

Correct two minor issues in the GSO programmer's guide:
- a note is rendered incorrectly in the middle of an unordered list;
  this results in the remainder of the list appearing inside the note.
  Correct indentation of the note to resolve same.
- two minor visual artifacts are present in the 'three-part-output-segment'
  diagram. Remove same.

Fixes: f6010c7 ("doc: add GSO programmer's guide")

v2:
- Move note back to original position.
- Remove link to note, as it is no longer needed.
- Correct note's indentation, inline with text.

Correct two minor issues in the GSO programmer's guide:
- a note is rendered incorrectly in the middle of an unordered list;
  this results in the remainder of the list appearing inside the note.
  Correct indentation of the note to resolve same.
- two minor visual artifacts are present in the 'three-part-output-segment'
  diagram. Remove same.

Fixes: f6010c7 ("doc: add GSO programmer's guide")

Acked-by: John McNamara <john.mcnamara@intel.com>

v3:
- Move note back to original position.
- Remove link to note, as it is no longer needed.
- Correct note's indentation, inline with text.

v2:
- Disregard - sent in error.
