[PATCH 0/4] devtools: align trailer checks with kernel convention

[Stephen Hemminger <stephen@networkplumber.org>]

This series makes four incremental changes to check-git-log.sh to
align DPDK's commit message trailer handling with the Linux kernel
convention.

The motivation came from the recent work in kernel where the
same patch needed different trailer formatting for DPDK vs. the kernel.
This is unnecessary friction for developers who work across both
projects.

Patch 1: Use git's built-in %(trailers) format instead of grepping
  the commit body with hand-rolled patterns.

Patch 2: Recognize the kernel trailer tags that DPDK was missing:
  Co-developed-by, Closes:, and Link:.  Also adds proper format
  validation for Cc:, Coverity issue:, and Bugzilla ID: tags.

Patch 3: Remove the blank line requirement between relation tags
  (Fixes, Cc) and attribution tags (Signed-off-by).  All trailers
  now form a single contiguous block, matching kernel convention
  and git-interpret-trailers(1) semantics.

Patch 4: Demote tag ordering from error to warning, since the
  kernel itself does not enforce strict ordering via tooling.

Stephen Hemminger (4):
  devtools: use git trailer parser for tag extraction
  devtools: recognize kernel trailer tags
  devtools: remove blank line requirement between trailers
  devtools: demote tag ordering to warning
