[PATCH 4.9 10/30] nvmet: dont overwrite identify sn/fr with 0-bytes

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Martin Wilck <mwilck@xxxxxxxx>

commit 42819eb7a0957cc340ad4ed8bba736bab5ebc464 upstream.

The merged version of my patch "nvmet: don't report 0-bytes in serial
number" fails to remove two lines which should have been replaced,
so that the space-padded strings are overwritten again with 0-bytes.
Fix it.
