The patch replaces dev_dbg() by dev_err(), so the user could actually see the
error, instead of wondering why w1 doesn't work.  The root cause of the bus
reset error isn't yet debugged though, but this sometimes happens on iPaq
H5555.

And while I'm at it, some cosmetic cleanups also made (few lines were using
spaces instead of tabs).
