Documentaiton:

A Co-Developed-by: states that the patch was also created by another developer
along with the original author. This is useful at times when multiple people
work on a single patch. Note, this person also needs to have a Signed-off-by:
line in the patch as well.

Please fix all over the place.

Please make these tabular aligned for readility sake

Please do not use tail comments. Either put the comment above the define or
use kernel doc.

See above.
