2 redundant ret assignments removed:
* 'ret = 1' before the logic 'if (data_maps)', and if any errors jump to
label 'done'. No 'ret = 1' needed before the error jump.
* After the '/* load programs */' part, if everything goes well, then
the BPF code will be loaded and 'ret' set to 0 by load_and_attach().
If something goes wrong, 'ret' set to none-O, the redundant 'ret = 0'
after the for clause will make the error skipped.
For example, if some BPF code cannot provide supported program types
in ELF SEC("unknown"), the for clause will not call load_and_attach()
to load the BPF code. 1 should be returned to callees instead of 0.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
