Subject: [PATCH 5/5] smack: Remove redundant assignments
Date: Thu, 31 Mar 2022 19:33:58 +0200	[thread overview]
Message-ID: <20220331173358.40939-5-michalorzel.eng@gmail.com> (raw)
In-Reply-To: <20220331173358.40939-1-michalorzel.eng@gmail.com>

Get rid of redundant assignments which end up in values not being
read either because they are overwritten or the function ends.

Reported by clang-tidy [deadcode.DeadStores]
