![]() All callers from other files ignore the return value of this function. And it can only ever return a non-zero value if the parameter card is NULL. Move the check for card being NULL into snd_card_free_when_closed() to keep the previous behaviour. Note this isn't necessary for snd_card_disconnect_sync() because if card was NULL in there the dereference of card for dev_err() would oops the kernel. Replace this by an oops triggered by the dereference of card for spin_lock_irq().
