[PATCH v2] firmware: hardcode the debug message for -ENOENT

From: yuankuiz
Date: Tue Feb 19 2019 - 21:39:07 EST

From: John Zhao <yuankuiz@xxxxxxxxxxxxxx>

When no file /path was found, the error code of -ENOENT
enumerated in errno-base.h, is returned. Stating clearly that
the file was not found is much more useful for debugging, So
let's be explicit about that.
