ASoC: soc-devres: add devm_snd_soc_register_dai()
The registration of DAIs may be done at two distinct times, once during a component registration and later when loading a topology. Since devm_ managed resources are freed in the reverse order they were allocated, when a component starts unregistering DAIs by walking through the DAI list, the memory allocated for the topology-registered DAIs was freed already, which leads to 100% reproducible KASAN use-after-free reports. This patch suggests a new devm_ function to force the DAI list to be updated prior to freeing the memory chunks referenced by the list pointers.
