FSF addresses used in PA sources are no longer valid and rpmlint generates numerous warnings during packaging because of this. This patch changes all FSF addresses to FSF web page according to the GPL how-to: https://www.gnu.org/licenses/gpl-howto.en.html Done automatically by sed-ing through sources.

/* This is a helper function that is called from pa_sink_input_new() and
|
|
* pa_source_output_new(). The job of this function is to figure out what
|
|
* channel map should be used for interpreting the volume that was set for the
|
|
* stream. The channel map that the client intended for the volume may be
|
|
* different than the final stream channel map, because the client may want the
|
|
* server to decide the stream channel map.
|
|
*
|
|
* volume is the volume for which the channel map should be figured out.
|
|
*
|
|
* original_map is the channel map that is set in the new data struct's
|
|
* channel_map field. If the channel map hasn't been set in the new data, then
|
|
* original_map should be NULL.
|
|
*
|
|
* format is the negotiated format for the stream. It's used as a fallback if
|
|
* original_map is not available.
|
|
*
|
|
* On success, the result is saved in volume_map. It's possible that this
|
|
* function fails to figure out the right channel map for the volume, in which
|
|
* case a negative error code is returned. */
