Subject: [PATCH] Kconfig: Add KCONFIG_STRICT mode
|
||
|
|
|
||
|
|
This is basically a -Werror mode for Kconfig. When exporting
|
||
|
|
KCONFIG_STRICT in the Makefile, warnings in Kconfig will produce
|
||
|
|
errors instead.
|
||
|
|
|
||
|
|
This will make it easier to spot unclean Kconfig files, settings
|
||
|
|
and dependencies.
|
||
|
|
|
