Subject: [PATCH net-next 04/10] net: netcp: remove the redundant memmov()
Date: Tue, 20 Dec 2016 17:09:47 -0500	[thread overview]
Message-ID: <1482271793-7671-5-git-send-email-m-karicheri2@ti.com> (raw)
In-Reply-To: <1482271793-7671-1-git-send-email-m-karicheri2@ti.com>

The psdata is populated with command data by netcp modules
to the tail of the buffer and set_words() copy the same
to the front of the psdata. So remove the redundant memmov
function call.
