The SmmLockBox driver in "MdeModulePkg/Universal/LockBox/SmmLockBox/SmmLockBox.inf" currently specifies a DepEx on EFI_SMM_SW_DISPATCH2_PROTOCOL. However, the driver doesn't use this protocol at all, either directly or indirectly. It calls SmiHandlerRegister() [MdeModulePkg/Core/PiSmmCore/Smi.c] to register SmmLockBoxHandler() (which serves LockBox requests). In turn, the SMM Core function SmiHandlerRegister() is also implemented without EFI_SMM_SW_DISPATCH2_PROTOCOL. The DepEx has been present since the initial commit of the SmmLockBox driver (SVN r12029); it is probably superfluous. Let's remove it. (Alternatively, we could extend OvmfPkg/EmuSmmDxe to fake this protocol, and return EFI_UNSUPPORTED when any member is called.)
