Subject: [PATCH] bpf: remove redundant intiialization of variable stype
Date: Wed, 21 Jul 2021 12:56:30 +0100	[thread overview]
Message-ID: <20210721115630.109279-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

The variable stype is being initialized with a value that is never
read, it is being updated later on. The assignment is redundant and
can be removed.

Addresses-Coverity: ("Unused value")
