//! Bus Specific Driver Override Protocol
//!
//! This protocol matches one or more drivers to a controller. This protocol is
//! produced by a bus driver, and it is installed on the child handles of buses
//! that require a bus specific algorithm for matching drivers to controllers.
//! This protocol is used by the `EFI_BOOT_SERVICES.ConnectController()` boot
//! service to select the best driver for a controller. All of the drivers
//! returned by this protocol have a higher precedence than drivers found in
//! the general EFI Driver Binding search algorithm, but a lower precedence
//! than those drivers returned by the EFI Platform Driver Override Protocol.
//! If more than one driver image handle is returned by this protocol, then the
//! drivers image handles are returned in order from highest precedence to
//! lowest precedence.
