The recent change for a new sysfs tree with card* object breaks the /sys/class/sound tree if CONFIG_SYSFS_DEPRECATED is enabled. The device in each entry doesn't point the correct device object: /sys/class/sound ... |-- pcmC0D0c | |-- dev | |-- device -> ../../../class/sound/card0 | |-- pcm_class | |-- power | | `-- wakeup | |-- subsystem -> ../../../class/sound | `-- uevent Also, this change breaks some drivers (like sound/arm/*) referring card->dev directly to obtain the device object for memory handling. This patch reverts the semantics of card->dev to the former version, which points to a real device object. The card* object is stored in a new card->card_dev field, instead. The device parent is chosen either card->dev or card->card_dev according to CONFIG_SYSFS_DEPRECATED to keep the tree compatibility. Also, card* isn't created if CONFIG_SYSFS_DEPRECATED is enabled. The reason of card* object is a root of all beloing devices, and it makes little sense if each sound device points to the real device object directly.
