virtio_ring: Cut and paste bugs in vring_create_virtqueue_packed()
There is a copy and paste bug in the error handling of this code and it uses "ring_dma_addr" three times instead of "device_event_dma_addr" and "driver_event_dma_addr". Fixes: 1ce9e6055fa0 (" virtio_ring: introduce packed ring support") Reported-by: Robert Buhren <robert.buhren@sect.tu-berlin.de> Reported-by: Felicitas Hetzelt <file@sect.tu-berlin.de> Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Link: https://lore.kernel.org/r/X8pGRJlEzyn+04u2@mwanda Signed-off-by: Michael S.
