Subject: [PATCH 2/3] esp: remove redundant define esph
Date: Mon, 1 Oct 2018 11:16:08 +0200 [thread overview]
Message-ID: <20181001091609.16646-3-steffen.klassert@secunet.com> (raw)
In-Reply-To: <20181001091609.16646-1-steffen.klassert@secunet.com>
From: Haishuang Yan <yanhaishuang@cmss.chinamobile.com>
The pointer 'esph' is defined but is never used hence it is redundant
and canbe removed.
