Subject: [PATCH 1/3] arm64: constify icache_policy_str[]
Date: Tue, 13 Aug 2019 15:16:37 +0100 [thread overview]
Message-ID: <20190813141639.13476-2-mark.rutland@arm.com> (raw)
In-Reply-To: <20190813141639.13476-1-mark.rutland@arm.com>
The icache_policy_str[] array contains compile-time constant data, and
is never intentionally modified, so let's mark it as const.
