[PATCH v4 0/1] virtio-crypto: add Linux driver
v4: - rework unknow status bit handler by calling virtio_break_device(). [Cornelia] - convert space to tab in Kconfig. [Stefan] - rename virtio_crypto.c to virtio_crypto_core.c and then make the moudle named virtio_crypto.ko for consistency. [Stefan] - don't call virtcrypto_dev_stop() on failure path. [Stefan] - don't add two empty lines. [Michael] - fix possible race by add
