#     Merge tag 'kconfig-v5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
#     
#     Pull Kconfig updates from Masahiro Yamada:
#     
#      - error out if a user specifies a directory instead of a file from
#        "Save" menu of GUI interfaces
#     
#      - do not overwrite .config if there is no change in the configuration
#     
#      - create parent directories as needed when a user specifies a new file
#        path from "Save" menu of menuconfig/nconfig
#     
#      - fix potential buffer overflow
#     
#      - some trivial cleanups
#     
#     * tag 'kconfig-v5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
#       kconfig: make conf_get_autoconfig_name() static
#       kconfig: use snprintf for formatting pathnames
#       kconfig: remove useless NULL pointer check in conf_write_dep()
#       kconfig: make parent directories for the saved .config as needed
#       kconfig: do not write .config if the content is the same
#       kconfig: do not accept a directory for configuration output
#       kconfig: remove trailing whitespaces
#       kconfig: Make nconf-cfg.sh executable
