[PATCH 2/4] ALSA: line6: Pass toneport pointer to toneport_has_led()

From: Chris Rorvick
Date: Fri Feb 06 2015 - 09:53:12 EST


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.
