* Avoid confusing the user by returning -EIO instead of -ENOENT in
efivarfs if an EFI variable gets deleted from under us and return EOF
when reading from a zero-length file - Lingzhu Xiang
* Fix an oops in efivar_update_sysfs_entries() caused by reusing (and
therefore corrupting) a kzalloc() allocation - Seiji Aguchi
* Initialise the DataSize argument to GetVariable() otherwise it will
not be updated with the actual size of the variable on return.
