This is needed if we wish to change the size of the resource structures.

cx88-alsa was resetting the card on load, causing the IRQ IR handler
to go away (maybe others, too). There's no actual need to reset the
card, though, so that line was removed

Video_buf were concerned to allow PCI devices to be used as
video capture devices. This patch extends video_buf features
by virtualizing pci-dependent functions and allowing other
type of devices to use it.
It is still DMA centric, although it may be used also by
devices that emulates scatter/gather behavior or a DMA device

If the call to cx88_core_get returns a NULL value, it is dereferenced
by cx88_reset, and perhaps by cx88_core_put. Spotted by the Coverity
checker.

- Not sure what went wrong here, but SND_PCI_PM_CALLBACKS got deleted.

- Static vars are equal to zero by default. Removed unnecessary =0 from them,
saving some data space

- This module is co-authored by Ricardo Cerqueira <v4l@cerqueira.org>.
- Added digital audio support for cx88-based boards that have function
01 enabled. These boards can be identified by having PCI id 1471:8801
or 1471:8811.
- Increased DMA buffer from 512 to 4096 seems to fix audio distortion.
- Existing audio DMA uses conflict with cx88-alsa. Should be disabled when
cx88-alsa module is compiled.
