[RFC PATCH sound] ALSA: usb-audio: scarlett2: snd_scarlett_gen2_controls_create() can be static

[Geoffrey D. Bennett]

Hi Takashi,

This patch seems legitimate to me (although I would adjust whitespace
so the second line doesn't go over 80 chars). Do you want to just
apply it as-is, or do you want me to send a second version of my patch
without this problem or send a new patch similar to this one?

Also sorry I don't know what the etiquette is in cc's for this message
:(. The message from kernel test robot was sent to a lot of people who
I don't think would be interested in this, so I trimmed the cc list
down.

Thanks,
Geoffrey.
