Wang Sheng-Hui c0885f61bb samples, bpf: remove redundant ret assignment in bpf_load_program()
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.

README

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.
