Expose make checkpatch through the common C source/header policy,
including userspace and KUnit sources. DIFFBR selects whole changed
files. Use the kernel's Checkpatch and companion data with --strict,
without adding diagnostic exceptions or loading local configuration.
Retain raw output and require native totals and a completion record
for every selected file. Distinguish source findings from unreadable
inputs, inconsistent reports and tool failures, with isolated fixtures.
Keep native caches in a temporary directory and serialize only this
analyzer's reports so it can run alongside the Kbuild analyzers.
Make checkpatch_scan use this target's implementation and exit status
instead of suppressing errors. Preserve the separate existing policy
of patch/commit helpers and the kernel regression runner.
Keep source inventory, cleanup and shell lint helpers together. Update the
Makefile, Debian packaging, scstadmin and the kernel, release and existing
checkpatch callers in the same commit so each consumer uses a valid path.
Keep run-shellcheck rooted at scripts/ after the move, preserving its
coverage of all tracked Bash helpers. Source selection and the existing
checkpatch exclusions are unchanged.
- Switching from 'set -e' to 'set -euo pipefail' for better error handling.
- Quoting all variable expansions to prevent word splitting and globbing.
- Replacing legacy unquoted $(...) and $@ with quoted forms.
- Using array-safe idioms where necessary (e.g., "${src_files[@]}").
This patch doesn't change any functionality.
