X-Git-Tag: next-20120913~66^2~3 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=406b52e1935ab350e137e275d08861ca66912f7f;p=karo-tx-linux.git virtio: add help to CONFIG_VIRTIO option. Trying to enable a virtio driver (eg CONFIG_VIRTIO_BLK) is painful because it depends on CONFIG_VIRTIO. CONFIG_VIRTIO doesn't tell you how to turn it on (it's selected from anything which provides a virtio bus). This patch at least adds some documentation, visible in menuconfig, as a hint.
