Changes in v2:

  * return true/false instead of 1/0
  * do not include spaces in driver name
  * drop patch altering struct names (unnecessary)

[PATCH v2 1/3] ALSA: line6: Add toneport_has_source_select()

[Chris Rorvick]

Add a predicate for testing if the device supports source selection to
make the conditional logic around this a bit cleaner.

[PATCH v2 2/3] ALSA: line6: Pass toneport pointer to toneport_has_led()

[Chris Rorvick]

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.

[PATCH v2 3/3] ALSA: line6: Pass driver name to line6_probe()

[Chris Rorvick]

Provide a unique name for each driver instead of using "line6usb" for
all of them.  This will allow for different configurations based on the
driver type.
