For header files it shouldn't matter if you include linux/module.h
followed by linux/init.h or the other way around. If you have them in
one place and sorted you can easily find out where to put the next one
and tell whether a specific header file is allready included. You also
make it a little harder to include one header file twice. If you think
this does not happen, a quick grep over the scsi tree shows:

|$ fgrep -R '#include ' drivers/scsi/ | sort > sort.txt
|$ fgrep -R '#include ' drivers/scsi/ | sort -u > sort-u.txt
|$ diff -u sort.txt sort-u.txt

SCSI was just a random example.
