Subject: [net-next v1 2/8] net: netcp: remove the redundant memmov()
Date: Fri, 6 Jan 2017 15:37:40 -0500 [thread overview]
Message-ID: <1483735066-14632-3-git-send-email-m-karicheri2@ti.com> (raw)
In-Reply-To: <1483735066-14632-1-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.
