Subject: [PATCH 17/18] locking/atomic: crypto: nx: remove redundant casts
Date: Wed, 22 May 2019 14:22:49 +0100
Message-ID: <20190522132250.26499-18-mark.rutland@arm.com> (raw)
In-Reply-To: <20190522132250.26499-1-mark.rutland@arm.com>

Now that atomic64_read() returns s64 consistently, we don't need to
explicitly cast its return value. Drop the redundant casts.
