This patch is for stable only. Commit 5a09df20872c ("scripts/dtc: Update
to upstream version v1.7.2-69-g53373d135579") upstream applied it as
part of a regular scripts/dtc sync, which may be unsuitable for older
versions of stable where the warning it fixes is present.

A recent strengthening of -Wunused-but-set-variable (enabled with -Wall)
in clang under a new subwarning, -Wunused-but-set-global, points out an
unused static global variable in dtc-lexer.lex.c (compiled from
dtc-lexer.l):

    641 | static int dts_version = 1;
        |            ^

Remove it to clear up the warning, as it is truly unused.

Stefano reports that after commit 62089b804895 ("kbuild: rpm-pkg:

using rpm 4.20.0 fails with:

  RPM build errors:
      Dependency tokens must begin with alpha-numeric, '_' or '/': #�) = 0x0d000002

This error comes from the automatic requirements feature of rpm. The
-debuginfo subpackage has no dependencies, so disable this feature with
'AutoReq: 0' for this subpackage, avoiding the error. This matches the
official %_debug_template macro that rpm provides. While automatic

does.

Additionally, while in the area, add the manual debug information

[ Upstream commit 6d6b8b0e28c468263d7fcb071e5cb284ae343df2 ]

Commit 62089b804895 ("kbuild: rpm-pkg: Generate debuginfo package
manually") moved away from the built-in RPM machinery for generating
-debuginfo packages to a more manual way to be compatible with module
signing, as the built-in machinery strips the modules after the
installation process, breaking the signatures.

Unfortunately, prior to rpm 4.20.0, there is a bug where a custom %files
directive is ignored for a -debuginfo subpackage [1], meaning builds
using older versions of RPM (such as on RHEL9 or RHEL10) fail with:

  Checking for unpackaged file(s): /usr/lib/rpm/check-files .../rpmbuild/BUILDROOT/kernel-6.19.0_dirty-1.x86_64
  error: Installed (but unpackaged) file(s) found:
     /debuginfo.list
     /usr/lib/debug/.build-id/09/748c214974bfba1522d434a7e0a02e2fd7f29b.debug
     /usr/lib/debug/.build-id/0b/b96dd9c7d3689d82e56d2e73b46f53103cc6c7.debug
     /usr/lib/debug/.build-id/0e/979a2f34967c7437fd30aabb41de1f0c8b6a66.debug
    ...

To workaround this, restrict the manual debug info package creation
process to when it is necessary (CONFIG_MODULE_SIG=y) and possible (when
using RPM >= 4.20.0). A follow up change will restore the RPM debuginfo
creation process using a separate internal flag to allow the package to
be built in more situations, as RPM 4.20.0 is a fairly recent version
and the built-in -debuginfo generation works fine when module signing is
disabled.
