From c7139f9d46dfafbb7dee4a2a0650c645a42c7c83 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Fri, 27 Oct 2023 11:03:48 -0600 Subject: util/lint/kconfig_lint: Ignore C preprocessor macros in code To see which Kconfig symbols are actually used, and to verify that they're used correctly, kconfig_lint scans the C code. It gives an error if it sees a CONFIG(symbol) where the symbol doesn't exist. This creates a problem when a C preprocessor macro is created to match multiple Kconfig symbols. The simple solution here is to just ignore those C preprocessor macro definitions as beyond the scope of this linter.
