The UefiShell*CommandsLib instances have constructor functions that do something like: gHiiHandle = HiiAddPackages (...); ... ShellCommandRegisterCommandName (..., gHiiHandle, ...); and destructor functions that implement the following pattern: HiiRemovePackages (gHiiHandle); The -- semantic, not functional -- problem is that "gHiiHandle" is declared with type EFI_HANDLE, and not EFI_HII_HANDLE, in all of these library instances, even though HiiAddPackages() correctly returns EFI_HII_HANDLE, and HiiRemovePackages() takes EFI_HII_HANDLE. Once we fix the type of "gHiiHandle", it causes sort of a butterfly effect, because it is passed around widely. Track down and update all of those locations. The DynamicCommand lib instances use a similar pattern, so they are affected too. NOTE: in practice, this patch is a no-op, as both EFI_HII_HANDLE and EFI_HANDLE are typedefs to (VOID*). However, we shouldn't use EFI_HANDLE where semantically EFI_HII_HANDLE is passed around.
