Merge tag 'kbuild-fixes-v5.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull Kbuild fixes from Masahiro Yamada:
- Fix the truncated path issue for HAVE_GCC_PLUGINS test in Kconfig
- Move -Wunsligned-access to W=1 builds to avoid sprinkling warnings
for the latest Clang
- Fix missing fclose() in Kconfig
- Fix Kconfig to touch dep headers correctly when KCONFIG_AUTOCONFIG is
overridden.
* tag 'kbuild-fixes-v5.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
kconfig: fix failing to generate auto.conf
kconfig: fix missing fclose() on error paths
Makefile.extrawarn: Move -Wunaligned-access to W=1
kconfig: let 'shell' return enough output for deep path names
