[PATCH 1/1] efi: avoid NULL dereference if FilePath is NULL

2019-04-16 Thread Heinrich Schuchardt
The UEFI specification allows LoadImage() to be called with a memory location only and without a device path. In this case FilePath will not be set in the EFI_LOADED_IMAGE_PROTOCOL. So in function grub_efi_get_filename() the device path argument may be NULL. As we cannot determine the device path
