[Qemu-devel] [PATCH 1.0] ac97: don't override the pci subsystem id

[Gerd Hoffmann <kraxel@redhat.com>]

This patch removes the code lines which set the subsystem id for the
emulated ac97 card to 8086:0000.  Due to the device id being zero the
subsystem id isn't vaild anyway.  With the patch applied the sound card
gets the default qemu subsystem id (1af4:1100) instead.
