However, when rebasing, I discovered that Kuninori Morimoto had recently done that in a different way :) I am still submitting my change since it should allow multiple platform components on a dai_link, which is one of the FIXME note in soc-core. I have also added a check on the codecs component availability to align on what was done for platforms and cpus Change since v1 [0]: * Fix registartion typo * Rename dlc variable to codec/platform [0]: https://lkml.kernel.org/r/20190626133617.25959-1-jbrunet@baylibre.com Jerome Brunet (2): ASoC: soc-core: defer card registration if codec component is missing ASoC: soc-core: support dai_link with platforms_num != 1 include/sound/soc.h | 6 ++++ sound/soc/soc-core.c | 67 +++++++++++++++++++++----------------------- 2 files changed, 38 insertions(+), 35 deletions(-) -- 2.21.0 _______________________________________________ linux-amlogic mailing list linux-amlogic@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-amlogic ^ permalink raw reply [flat|nested] 5+ messages in thread
