ASoC: Fix check for symmetric rate enforcement
The ASoC core tries to not enforce symmetric rates when two streams open simultaneously. It does so by checking rtd->rate being zero. This works exactly once after booting because it is not set to zero again when the streams close. Fix this by setting rtd->rate when no active stream is left. [This leads to lots of warnings about not enforcing the symmetry in some situations as there's a race in the userspace API where we know we've got two applications but don't know what rates they want to set. -- broonie ] Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
