Looks fine to me.

I still need the changes to drivers/acpi/scan.c, but if you push this patch
upstream then I'll reroll my patch as a follow-on to yours...

...with the custom HID string #define'd in a header file someplace.

Actually, if you'll add a Signed-off-by line to your patch, I'll submit both of
them as a patchset and save you a little work. :)

Stylistic nit--would it be clearer to initialize id in the for loop instead of
at the beginning of the function?
