[dm-devel] [patch 2/2] multipath-tools: Intialize pointer passed to get_cmdvec

[Christof Schmitt <christof schmitt de ibm com>]

From: Christof Schmitt <christof schmitt de ibm com>

get_cmdvec can return before the vector argument has been initialized. Fix this
by initializing the pointer before passing it to get_cmdvec. This fixes a
segfault in the interactive mode when hitting the tab key directly on the
command prompt.
