      ASoC: soc-core: fix init platform memory handling · 09ac6a81
      Curtis Malainey authored
      snd_soc_init_platform initializes pointers to snd_soc_dai_link which is
      statically allocated and it does this by devm_kzalloc. In the event of
      an EPROBE_DEFER the memory will be freed and the pointers are left
      dangling. snd_soc_init_platform sees the dangling pointers and assumes
      they are pointing to initialized memory and does not reallocate them on
      the second probe attempt which results in a use after free bug since
      devm has freed the memory from the first probe attempt.
      
      Since the intention for snd_soc_dai_link->platform is that it can be set
      statically by the machine driver we need to respect the pointer in the
      event we did not set it but still catch dangling pointers. The solution
      is to add a flag to track whether the pointer was dynamically allocated
      or not.
