The C standard specifies that there is no need to cast from a pointer to
void [1].

The vast majority of the users of dev_set_drvdata do not cast their
pointers to void, and the few that do so should be fixed before it
spreads by following bad examples (which I was about to do here [2]).

The very specific cases where the cast avoids warnings (e.g. droping
const) have been kept as they are.
