From 7ad5039ee557f0a427a0768e43c28d0236d56ba3 Mon Sep 17 00:00:00 2001 From: Javier González Date: Fri, 30 Mar 2018 00:05:18 +0200 Subject: lightnvm: pblk: check for supported version MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit At this point, only 1.2 spec is supported, thus check for it. Also, since device-side L2P is only supported in the 1.2 spec, make sure to only check its value under 1.2.
