[U-Boot] [PATCH] UBIFS: Improve error message when reading superblock failed

[Bernhard Walle]

In addition to the error message also display the error code. I had the
problem that my malloc memory was not enough (ENOMEM), and if u-boot
had displayed the error code immediately that would have saved me some
debugging.
