4d572776d4 [ALSA] Remove redundant NULL checks before kfree

Checking a pointer for NULL before calling kfree() on it is redundant,
kfree() deals with NULL pointers just fine.
This patch removes such checks from sound/

This patch also makes another, but closely related, change.
It avoids casting pointers about to be kfree()'ed.

604cf49925 [ALSA] usb-audio - fix synchronization packet interval with Audigy 2 NX
USB generic driver
When a device does not provide the bRefresh field in its audio endpoint
descriptors, use the bInterval field instead.

Furthermore, increase the number of sync URBs for better queueing.

d3ff42fd2b [ALSA] usb-audio - claim all interfaces for Roland USB MIDI devices
USB generic driver
Many Roland USB MIDI devices have two interfaces that are currently not
used by the driver; claim them anyway.

29b16931f9 [ALSA] usb-audio - avoid unnecessary double buffering
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.

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.

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.

1da177e4c3 Linux-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!
