From: Randy Dunlap <[email protected]> When a driver kconfig symbol =m and it selects another symbol, that other symbol will also be =m (unless something else causes it to be =y), so when XEN_BLKDEV_FRONTEND=m and/or XEN_NETDEV_FRONTEND=m, then XEN_XENBUS_FRONTEND=m, but that won't build (build error message below). Changing XEN_XENBUS_FRONTEND from a tristate to a bool makes it be =y (builtin) any time that it is selected, so there is no build error.
