[GIT PULL 42/45] lightnvm: do no update csecs and sos on 1.2

From: Matias BjÃrling
Date: Tue Oct 09 2018 - 07:15:39 EST


From: Javier GonzÃlez <javier@xxxxxxxxxxx>

1.2 devices exposes their data and metadata size through the separate
identify command. Make sure that the NVMe LBA format does not override
these values.
