You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

For the other events, it is useless. Also, dealing with the codec to codec params just before calling .hw_params() callbacks give change to either party on the link to alter params content in .startup(), which might be useful in some cases Signed-off-by: Jerome Brunet Link: https://lore.kernel.org/r/20190725165949.29699-4-jbrunet@baylibre.com Signed-off-by: Mark Brown --- sound/soc/soc-dapm.c | 159 +++++++++++++++++++++++++------------------ 1 file changed, 92 insertions(+), 67 deletions(-) diff --git a/sound/soc/soc-dapm.c b/sound/soc/soc-dapm.c index 7db4abd9a0a5..6dcaf9ff6eb5 100644 --- a/sound/soc/soc-dapm.c +++ b/sound/soc/soc-dapm.c @@ -3764,25 +3764,59 @@ int snd_soc_dapm_new_controls(struct snd_soc_dapm_context *dapm, } EXPORT_SYMBOL_GPL(snd_soc_dapm_new_controls);
