[alsa-devel] [PATCH] ASoC: soc-core: fix crash when removing not instantiated card

[Mike Rapoport]

If the card was not instantiated in snd_soc_instantiate_card, calling
soc-remove will crash because some of codec, cpu_dai and card .remove
methods are called twice.
Fix this by returning from soc_remove immediately.
