USB generic driver
When a USB packet boundary falls exactly on a buffer boundary, hwptr
remains at the end of the buffer which causes an overflow in the next
iteration and triggers double buffering although the next packet would
actually be contiguous.
This patch ensures that hwptr is always smaller than buffer_size.

[ALSA] Adding support for ATI IXP450 HD Audio device support
Documentation,HDA Intel driver
This patch changes the Intel HD Audio device driver to include
the support of HD Audio device embedded in ATI south bridge
IXP450. Because the design of ATI chipset follows intel HD Audio
specification 1.0, the programming method is the same as that
of intel HD Audio device exception one minor change which requires
to enable snoop for DMA transport. There are 3 changes that have been
made to hda_intel.c file.
1. Added device ID for ATI HD Audio device;
2. Increase maximum CODEC supported to 4;
3. Enable snoop during the driver initialization.

AC97 Codec
The handling of shared surround/clfe output jacks with line/mic-in
on some AC97 codecs is improved.
Instead of 'Line-In As Surround' or 'Mic As Center/LFE' switch, two
new enum controls are introduced: 'Channel Mode' and 'Surround Jack Mode'.
The formar changes the current output mode among 2, 4 and 6-channels.
The latter controls whether the jacks are shared or independent.

Documentation,VIA82xx driver
Add support for full sample rate conversion capabilities of DXS

- any sample rate in the 8000 ... 48000 Hz range is supported even if
the AC'97 codec supports only 48000 Hz output;
- different DXS channels can use different sample rates at the same
time (the controller performs required sample rate conversion and
mixing in hardware).

it is not good for AC3 non-audio output.

HDA Codec driver
Patch by C.L. Tien <cltien@cmedia.com.tw>:
The patch makes cm9880 to choose multi-channel jacks automatically.
1. I found the current code has basic_init, which already includes
necessary controls for 6-stack initialization, so I don't need
another model.
2. I add a new model 'auto' to let the driver find a. if there are
option real panel/front panel, b. the jacks to be used for multichannel.
Because the jack color are based on MS's channel sequence, so the 'auto'
model will pick the same jacks for multichannel MS uses. I did this to
hope to minimize users questions. These code can also be applied to other
codecs but I don't have any to test.
