Xiaomeng Tong a55e2d7423 ALSA: cs4236: fix an incorrect NULL check on list iterator ... commit 0112f822f8 upstream. The bug is here: err = snd_card_cs423x_pnp(dev, card->private_data, pdev, cdev); The list iterator value 'cdev' will *always* be set and non-NULL by list_for_each_entry(), so it is incorrect to assume that the iterator value will be NULL if the list is empty or no element is found. To fix the bug, use a new variable 'iter' as the list iterator, while use the original variable 'cdev' as a dedicated pointer to point to the found element. And snd_card_cs423x_pnp() itself has NULL check for cdev.
