Hi, This series enables virtio-rng to service the early randomness requests made by the hwrng core (patch 2), with Herbert's idea of using the scan routine. Patch 3 reverts the previous restriction, which no longer applies, to not send read requests to the host before successful probe. Patch 1 is a minor cleanup. Please review and apply, Amit Shah (3): virtio: rng: remove unused struct

Hello, This series introduces a way to allow devices to contribute to initial system randomness after a certain delay. Specifically, the virtio-rng device can contribute initial randomness only after a successful probe(). A delayed workqueue item is queued in the system queue to fetch this randomness if the device indicates it's capable of contributing only after a delay, via the new
