Lots of cosmetic changes in order to sync the CVS with

the version that made it into the 2.5.68 kernel.
- remove unnecessary c++-style comments
- fixed some line breaks and the style function headers
are formatted: please don't argue with me about these changes,
I don't care how they are formatted.
- remove newline breaks between memory allocation and the return value
check

Some more interesing stuff:
- remove ddelay() functions completly, replace with set_current_state() and
manual schedule_timeout() calls.
- made some init data for the mxb driver static and global (patch already
send to lkml)

Some crucial changes:
- inherit some return values Mr. Alan Cox has changed -- please review
