Subject: Fixes brick Nova pep8 violation for lvm.py
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=9faa32599cf86c4111d0d6cd0a7c377061f2ee6d;p=openstack-build%2Fcinder-build.git

Fixes brick Nova pep8 violation for lvm.py

Running pep8 tests in Nova gives a violation
in lvm.py for not importing a module.  This
is a simple fix to import the module itself
instead of only importing a function in the
module.

Fixes bug #1220849
