Subject: [patch 3/4 v2] skd: use memcpy() as a cleanup
Date: Fri, 13 Sep 2013 12:53:10 +0000 [thread overview]
Message-ID: <20130913125310.GK25896@mwanda> (raw)
In-Reply-To: <CAMuHMdX88cUEu2dmamEttK=9Lv0TKiZauCtPDLbgKUde+8ufyQ@mail.gmail.com>
The code here is copying the version to inq.driver_version but we don't
want it to be NUL terminated. Instead we pad the rest of the array with
spaces. It's fewer lines to use memcpy() and maybe a little nicer.
