All struct members here are sized such that there is no padding needed, so
the packed attribute doesn't buy you anything - unless of course the
entire structure is missaligned but I don't see how that would be possible
in this driver so the __attribute__ ((packed)) should go - it result in
somwhat larger and slower code.

FWIW, a modern gcc will warn about such superfluous packed attributes,
that's another reason to remove those.

I doubt it will in this case; the packed structure is dereferenced by a
pointer so no way for gcc to know the alignment.
