Subject: [PATCH 4/4] stm32mp15: tidy up #ifdefs in cpu.c
Date: Mon, 11 Oct 2021 09:52:51 +0200 [thread overview]
Message-ID: <20211011075244.4.Id047d97a30c68f46ac2bcb57014faa42067dd1ba@changeid> (raw)
In-Reply-To: <20211011075244.1.Icb805e47dd8102559236013264342b52c187813f@changeid>
We should avoid #ifdef in C modules and the unused functions
are eliminated by the linker.
Use the more readable IS_ENABLE() instead.
