Thanks.
As another issue, I can see sparse (v0.5.0) errors:
sound/usb/line6/driver.c:274:43: error: cannot size expression
sound/usb/line6/driver.c:275:16: error: cannot size expression
sound/usb/line6/driver.c:276:16: error: cannot size expression
sound/usb/line6/driver.c:277:16: error: cannot size expression
And this fix can suppresses them:
$ git diff sound/usb/line6
diff --git a/sound/usb/line6/driver.c b/sound/usb/line6/driver.c
index f9224ec..ad7efc0 100644

};
EXPORT_SYMBOL_GPL(line6_midi_id);
Besides, there's a difference of the declaration between header and code:
$ cat sound/usb/line6/driver.h
...
extern const unsigned char line6_midi_id[3];
This is quite minor. So I can't judge to fix it or not... What do you
think about it?
