[ Upstream commit a314f52a0210730d0d556de76bb7388e76d4597d ]
Most 'make *config' commands use .config as the base configuration file.
When .config does not exist, Kconfig tries to load a file listed in KCONFIG_DEFCONFIG_LIST instead.
However, since commit b75b0a819af9 ("kconfig: change defconfig_list option to environment variable"), warning messages have displayed an incorrect file name in such cases.
Below is a demonstration using Debian Trixie. While loading /boot/config-6.12.9-amd64, the warning messages incorrectly show .config as the file name.
With this commit, the correct file name is displayed in warnings.
[Before]
$ rm -f .config $ make config # # using defaults found in /boot/config-6.12.9-amd64 # .config:6804:warning: symbol value 'm' invalid for FB_BACKLIGHT .config:9895:warning: symbol value 'm' invalid for ANDROID_BINDER_IPC
[After]
$ rm -f .config $ make config # # using defaults found in /boot/config-6.12.9-amd64 # /boot/config-6.12.9-amd64:6804:warning: symbol value 'm' invalid for FB_BACKLIGHT /boot/config-6.12.9-amd64:9895:warning: symbol value 'm' invalid for ANDROID_BINDER_IPC
