Subject: [PATCH 7/9] selinux: do not discard const qualifier in cast
Date: Tue, 25 Jan 2022 15:14:17 +0100	[thread overview]
Message-ID: <20220125141422.32655-6-cgzones@googlemail.com> (raw)
In-Reply-To: <20220125141422.32655-1-cgzones@googlemail.com>

Do not discard the const qualifier on the cast from const void* to
__be32*; the addressed value is not modified.

Reported by clang [-Wcast-qual]
