This is an ancient driver, unfortunately we prefer not to apply minor code cleanups of this nature unless they are a part of other development work. We'd be constantly tweaking the 200+ drivers we have, most of which get zero use.

It is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter). At the same time remove some unnecessary initializations and refactor a bit to make the code clearer. This patch has no effect on runtime behavior.
