Subject: [PATCH 2/3] staging: dgnc: Remove casting the return value which is a void pointer
Date: Mon, 09 Sep 2013 14:18:55 +0900 [thread overview]
Message-ID: <004901cead1c$14c97680$3e5c6380$%han@samsung.com> (raw)
In-Reply-To: <004301cead1b$e3272a00$a9757e00$%han@samsung.com>
Casting the return value which is a void pointer is redundant.
The conversion from void pointer to any other pointer type is
guaranteed by the C programming language.
