Hi,

I'm investigating switching videolan's OSS-style audio-capture (used to 
complement streaming from a v4l source) to use the alsa-oss oss-redir 
abstraction layer.  Whilst writing the patch, I came up against the 
quirk that

i_fd = oss_pcm_open(devname, O_RDONLY | O_NONBLOCK)

doesn't return a non-blocking file descriptor.  This is a bit of a 
showstopper, as vlc relies on the fd being nonblocking in order for the 
thread to yield to allow interleaved video capture to occur.

The problem appears to be a typo in alsa-oss/alsa/pcm.c:oss_dsp_open(), 
where the mode parameter rather than the oflags parameter is checked for 
the O_NONBLOCK flag.  I've included a trivial patch to fix it.

cheers;

M.
