Series [v3,1/5] virtio-crypto: use private buffer for control request | expand

Commit Message

zhenwei pi April 21, 2022, 10:40 a.m. UTC 
Move virtcrypto_clear_request and virtcrypto_dataq_callback into
virtio_crypto_common.c to make code clear. Then the xx_core.c
supports:
  - probe/remove/irq affinity seting for a virtio device
  - basic virtio related operations

xx_common.c supports:
  - common helpers/functions for algos
