3.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Sakamoto <o-takashi@xxxxxxxxxxxxx>
commit f2b14c0bc510c6a8f67a4f36049deefe5d99a537 upstream.
The amdtp_stream_wait_callback() doesn't return minus value and
the return code is not for error code.
This commit fixes with a propper condition and an error code.
Fixes: f3699e2c7745 ('ALSA: oxfw: Change the way to start stream')
