[patch 47/47] ALSA: mtpav - Fix initial value for input hwport

[Greg KH]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Takashi Iwai <tiwai@xxxxxxx>

commit 32cf9a16f4af01573ddec1eb073111fc20a9d7d4 upstream.

Fix the initial value for input hwport.  The old value (-1) may cause
Oops when an realtime MIDI byte is received before the input port is
explicitly given.
Instead, now it's set to the broadcasting as default.
