We need to cast somewhere anyway so we may as well cast from 'void *' to
'unsigned int' where needed and not the other way around (or rather from
'unsigned int' to 'struct ide_timing *') -- which would be an ugly hack
and could cause maintainability/portability problems later.
BTW it seems like a good occasion to add ide_{get,set}_drivedata()
helpers
(ala existing ide_{get,set}_hwifdata() ones) to <linux/ide.h> and thus
make
internal IDE API more coherent.
[ Yes, I know that we may get away with s/unsigned int/unsigned long/
and casting it to 'struct ide_timing *' for now but it always better
to at least consider more elegant solution first... ]
Changing a lot of drivers is more elegant than not? Doubt it.
And don't tell me this patch is "elegant"... :-/
Well, it is makes code more coherent and more maintainable...
Moreover those inline helpers serve as a part of documentation (though
real DocBook documentation would also be nice) for host drivers authors.
Either this or we should remove ide_{get,set}_hwifdata() and allow
host drivers to poke directly also at hwif->hwif_data...
Seems like a good idea. I'm not sure why these fields should be special.
