Subject: [PATCH 2/9] efi/libstub/x86: remove redundant assignment to pointer hdr
Date:   Thu,  9 Apr 2020 15:04:27 +0200
Message-Id: <20200409130434.6736-3-ardb@kernel.org>
In-Reply-To: <20200409130434.6736-1-ardb@kernel.org>
References: <20200409130434.6736-1-ardb@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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

The pointer hdr is being assigned a value that is never read and
it is being updated later with a new value. The assignment is
redundant and can be removed.

Addresses-Coverity: ("Unused value")
