Okay, the whole line seemed redundant for that's always true.

I also prefer using whole name with mediatek as the prefix than just abbreviation used. I will update it also in the next version. As for the file naming for other drivers, i feel it's okay for me changing into mediatek as file prefix, but it still depends on maintainers or original authors if they likes this.
