Tom Stellard 7e7d5bfbbe bpftool: Fix -Wuninitialized-const-pointer warnings with clang >= 21 
[ Upstream commit 5612ea8b55 ]

This fixes the build with -Werror -Wall.

btf_dumper.c:71:31: error: variable 'finfo' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]
   71 |         info.func_info = ptr_to_u64(&finfo);
      |                                      ^~~~~

prog.c:2294:31: error: variable 'func_info' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]
 2294 |         info.func_info = ptr_to_u64(&func_info);
      |

v2:
  - Initialize instead of using memset.

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 reStructuredText 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.
