From a quick grep of the source, it looks like a contributing factor is Matsushita Electric Industrial. If you are interested, I posted the output of grep to pastebin [0].

EDIT: This is against linux-3.8.0 from Mint's repository.

The group's name has change from Matsushita to Panasonic, so this would bring the count down in the future.

I doubt they retroactivly change code/comments because the original organization changed their name. The Matsushita references will probably stay there until they bitrot and get removed/rewritten.
