[PATCH] Prevent trident driver from grabbing pcnet32 hardware

Some pcnet32 hardware erroneously has the Vendor ID for Trident.  The
pcnet32 driver looks for the PCI ethernet class before grabbing the
hardware, but the current trident driver does not check against the PCI
audio class.  This allows the trident driver to claim the pcnet32 hardware.
 This patch prevents that.

This revised version of the OSS Trident patch includes PCI_DEVICE Macro
usage.
