ALSA: line6: Pass toneport pointer to toneport_has_led()
It is unlikely this function would ever be used in a context without a pointer to a `struct usb_line6_toneport', so grab the device type from it rather than having the caller do it. Signed-off-by: Chris Rorvick <chris@rorvick.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
