[ Upstream commit 02a4694107b4c830d4bd6d194e98b3ac0bc86f29 ] We are missing setting error code in do_loader() when bpf_object__open_file() fails. This means the command's exit status code will be successful, even though the operation failed. So make sure to return the correct error code. To maintain consistency with other locations where bpf_object__open_file() is called, return -1.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
