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.

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.

Some HP OmniBook laptops (500 and 6000 at least) require some GPIO magic

Something is still missing to make them work perfectly. However I have been
