Modules: EMU10K1/EMU10K2 driver
Description:
Part way to fix ALSA bug#927
Add support for the SPI interface on the CA0108 chip.
This is used to control the registers on the DAC.
Headphone output tested.
Other outputs and Capture not tested yet.
Note: The red LED does not come on, but sound is still OK.

Modules: ALSA sequencer
Reduce the maximum possible number of global clients to 16 to make
more numbers available for card clients, and allow dynamically allocated
card client numbers to share the same range as application client
numbers to make sure that all 32 cards can be used at the same time.

All users of snd_seq_create_kernel_client() have to set the client name
anyway, so we can just pass the name as parameter. This relieves us
from having to muck around with a struct snd_seq_client_info in these
cases.

The fields of struct snd_seq_client_callback either aren't used or are
always set to the same value, so we can get rid of it altogether.

Modules: AC97 Codec,ATIIXP driver,Intel8x0 driver
This patch adds a new quirk for ac97 hardware that combines the existing
AC97_TUNE_MUTE_LED and AC97_TUNE_HP_ONLY quirks. This is needed for several
current HP laptops. Additionally, it adds the HP nx6125 to the
AC97_TUNE_MUTE_LED list.
Fixed for the latest version of ALSA by Takashi Iwai <tiwai@suse.de>.

Distorted sound now comes from the Audio Out socket. Still more work to do.

With dynamic minor numbers, we can increase the number of sound cards.
This requires that the sequencer client numbers of some kernel drivers
are allocated dynamically, too.

Modules: ALSA Core,ALSA Minor Numbers
Add an option to allocate device file minor numbers dynamically.

Instead of storing the pointers to the device-specific structures in an
array, put them into the struct snd_minor, and look them up dynamically.
This makes the device type modules independent of the minor number
encoding.

Modules: ALSA Core
Store the snd_minor structure pointers in one array instead of using a
separate list for each card. This simplifies the mapping from device
files to minor struct by removing the need to know about the encoding
of the card number in the minor number.

Instead of a comment string, store the device type in the snd_minor
structure. This makes snd_minor more flexible, and has the nice side
effect that we don't need anymore to create a separate snd_minor
template for registering a device but can pass the file_operations
directly to snd_register_device().

Modules: ALSA Core,Control Midlevel,/oss/Makefile
Remove the centralized PM control in the sound core.
Each driver is responsible to get callbacks from bus/driver now.
SND_GENERIC_DRIVER is removed together with this action.

Backward-compatibility typedefs are stored in the new header, typedefs.h,
for out-of-tree drivers. This will be removed in future.
