Subject: policy.c: Fix for compiler error
X-Git-Tag: mdadm-4.2-rc1~122
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=757e55435997e355ee9b03e5d913b5496a3c39a8;p=thirdparty%2Fmdadm.git

policy.c: Fix for compiler error

After cd72f9d(policy: support devices with multiple paths.) compilation
on old compilers fails because "‘p’ may be used uninitialized
in this function".

Initialize it with NULL to prevent this.
