[PATCH] Driver: Replace switch cases with ifs.

[Rui Ueyama]

Do you think they still stand?

(a) is a matter of taste, but well, if something can be written using if, I
wouldn't convert it to a switch. (b) is not a matter -- OptTable handles
optional arguments for you. For (c) we didn't do duplication check.
