This patch adds a struct device pointer to struct snd_pcm in order to be able to give it a different device than the card. It defaults to the card's device, however, so it should behave identically for drivers not touching the field.

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.

Converts from using struct "class_device" to "struct device" making everything show up properly in /sys/devices/ with symlinks from the /sys/class directory. It also makes the struct sound_card to show up as a "real" device where all the different sound class devices are placed as childs and different card attribute files can hang off of. /sys/class/sound is still a flat directory, but the symlink targets of all devices belonging to the same card, point the the /sys/devices tree below the new card device object.

Alsa used to kmalloc one file->f_op per file per disconnecting snd_card. This led to oopses sometimes when file->f_op was freed before __fput() finished. Patch adds a virtual device for disconnect: VDD. VDD consists of: LIST_HEAD(shutdown_files) protected by DEFINE_SPINLOCK(shutdown_mutex) static struct file_operations snd_shutdown_f_ops and functions assigned to it Additions to struct snd_monitor_file to specify if instance is hidden by VDD or not. A VDD's instance is created in snd_card_disconnect() under the card->files_lock. cleaned up in snd_card_file_remove() under the card->files_lock.

Add maximum latency tracking to the ALSA subsystem for PCM playback. In ALSA, the playback application controls the buffer size and thus indirectly the period of latency that it can deal with. This patch uses 75% of the total available latency as threshold to announce to the latency subsystem; While 75% is a crude heuristic it's a quite reasonable one; the remaining 25% can be used for all driver processing for the next samples which is also proportional to the size of the buffer. With ogg123 a latency setting of about 4msec was seen (at 44Khz), while with the "play" command a much longer maximum tolerable latency was seen. Other, more multimedia oriented players as well as games, will have a lot smaller buffers to allow better synchronization and those will actually get into the latency domains where there is impact on the power management rules.
