Pull Kconfig updates from Masahiro Yamada: - always require argument for --defconfig and remove the hard-coded arch/$(ARCH)/defconfig path - make arch/$(SRCARCH)/configs/defconfig the new default of defconfig - some code cleanups * tag 'kconfig-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: kconfig: remove meaningless if-conditional in conf_read() kconfig: Fix spelling of sym_is_changable unicore32: rename unicore32_defconfig to defconfig kconfig: make arch/*/configs/defconfig the default of KBUILD_DEFCONFIG kconfig: add static qualifier to expand_string() kconfig: require the argument of --defconfig kconfig: remove always false ifeq ($(KBUILD_DEFCONFIG,) conditional
