3a2f08560d [ALSA] usb-audio - enable high speed (not) on Audigy 2 NX
USB generic driver
The SB Audigy 2 NX needs a special boot-up command before it works in
high speed mode.

However, we don't actually enable it yet because high speed
synchronization doesn't seem to work with this device.

c3f9329716 [ALSA] usb-audio - set sample rate attribute on Audigy 2 NX endpoints
USB generic driver
The SB Audigy 2 NX does not advertise the sample rate attribute in its
endpoint descriptors although it supports it.

ca81090a00 [ALSA] usb-audio - use only one packet in synchronization feedback URBs
USB generic driver
Do not use more than one packet in synchronization feedback URBs because
it would be pointless to send or receive more than one value at the same
time.

1149a64fe4 [ALSA] usb-audio - use proper interval between synchronization packets
USB generic driver
Add sanity checks when reading the bRefresh value, and actually use it
for the synchronization packets instead of polling at 1000 Hz.

27d10f5664 [ALSA] usb-audio - cache vendor/product IDs
USB generic driver
Cache the decoded values of idVendor/idProduct to get rid of most of
those ugly le16_to_cpu() calls.

8c1872dcf2 [ALSA] usb-audio - restrict Audigy 2 NX frequencies to 48/96 kHz
USB generic driver
On the SB Audigy 2 NX, frequency feedback doesn't quite work
when playing at 44.1 kHz, so temporarily disable this frequency.

230cd5e248 [ALSA] prevent oops & dead keyboard on usb unplugging while the device is being used
USB generic driver,USB USX2Y
Without this patch, some usb kobjects, which are parents to
the usx2y's kobjects can be freed before the usx2y's.
This led to an oops in get_kobj_path_length() and a dead
keyboard, when the usx2y's kobjects were freed.
The patch ensures the correct sequence.
Tested ok on kernel 2.6.12-rc2.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
