[ 256/262] ALSA: snd-usb: fix next_packet_size calls for pause case

[Greg Kroah-Hartman]

From: Greg KH <gregkh@xxxxxxxxxxxxxxxxxxx>

3.5-stable review patch.  If anyone has any objections, please let me know.

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

From: Daniel Mack <zonque@xxxxxxxxx>

commit 8dce30c89113e314d29d3b8f362aadff8087fccb upstream.

Also fix the calls to next_packet_size() for the pause case. This was
missed in 245baf983 ("ALSA: snd-usb: fix calls to next_packet_size").
