Subject: mdadm/test: use the first element of array as parsing condition
X-Git-Tag: mdadm-4.1-rc1~91
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3af7f2adc097fad519273a817c3ae6ac1f66d32f;p=thirdparty%2Fmdadm.git

mdadm/test: use the first element of array as parsing condition

it would complain "too many arguments" when array[] has
few members, it's proper to check whether or not array[0]
is null.
