I'd like to know why finding the current device would ever fail?

I see at least two valid reason :

  1. In case of a bad/incomplete EFI implementation (like U-Boot currently)
  2. In embedded world you could have uboot + loader.efi in a SPI flash for example and this device would not be exposed as an EFI disk.

I would rather put this logic in find_currdev() itself.

Should we go with @jhb's suggestion then?

I'm good either way, though jhb's method is cleaner.

Totally forgot about this review, I'll update it this weekend with @jhb suggestion.
