[PATCH net] vsock/virtio: enable VQs early on probe

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



virtio spec requires drivers to set DRIVER_OK before using VQs.
This is set automatically after probe returns, but virtio-vsock
driver uses VQs in the probe function to fill rx and event VQs
with new buffers.

Let's fix this, calling virtio_device_ready() before using VQs
in the probe function.
