.SH NAME
ac97_probe_codec \- Initialize and setup AC97-compatible codec
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
int ac97_probe_codec  (struct ac97_codec * \fIcodec\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIcodec\fB\fR
(in/out) Kernel info for a single AC97 codec
.SH "DESCRIPTION"
.PP
Reset the AC97 codec, then initialize the mixer and
the rest of the \fIcodec\fR structure.
.PP
The codec_read and codec_write fields of \fIcodec\fR are
required to be setup and working when this function
is called.  All other fields are set by this function.
.PP
codec_wait field of \fIcodec\fR can optionally be provided
when calling this function.  If codec_wait is not NULL,
this function will call codec_wait any time it is
necessary to wait for the audio chip to reach the
codec-ready state.  If codec_wait is NULL, then
the default behavior is to call schedule_timeout.
Currently codec_wait is used to wait for AC97 codec
reset to complete. 
.PP
Returns 1 (true) on success, or 0 (false) on failure.
