From 9147d2ad8abb73cea5799323fc73ccdaf675826f Mon Sep 17 00:00:00 2001
From: Stanislav Brabec <sbrabec@suse.cz>

Subject: [PATCH] blockdev: Don't fail on missing start sector

It causes
 # blockdev --report" error:
 blockdev: /dev/dm-9: failed to read partition start from sysfs: No such file or directory

There is no reliable way to detect a geometry in this case. Report N/A
instead.
