Subject: [PATCH 15/16] kconfig: implement IF_ENABLED helper
Date: Tue, 1 Apr 2025 12:48:05 +0200 [thread overview]
Message-ID: <20250401104806.3959859-16-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20250401104806.3959859-1-a.fatoum@pengutronix.de>
For situations where ternary operations are not allowed like
compile-time string concatenation, introduce a helper that checks if the
first argument is enabled and expands to the rest of the arguments only
if it is.
