If anyone has any objections, please let me know. ------------------ From: Cezary Rojewski [ Upstream commit 3f100f524e75586537e337b34d18c8d604b398e7 ] For the classic snd_hda_intel driver, codec->card and bus->card point to the exact same thing. When snd_card_diconnect() fires, bus->shutdown is set thanks to azx_dev_disconnect(). card->shutdown is already set when that happens but both provide basically the same functionality. For the DSP snd_soc_avs driver where multiple codecs are located on multiple cards, bus->shutdown 'shortcut' is not sufficient. One codec card may be unregistered while other codecs are still operational. Proper check in form of card->shutdown must be used to verify whether the codec's card is being shut down.
