Subject: [PATCH] Init devlist as an array
Git-commit: 8063fd0f9e8abd718bd65928c19bc607cee5acd8
Patch-mainline: mdadm-4.1+
References: jsc#SLE-10078, jsc#SLE-9348

devlist is an string. It will change to an array if there is disk that
is sbd disk. If one device is sbd, it runs devlist=().
This line code changes devlist from a string to an array. If there is
no sbd device, it can't run this line code. So it will still be a string.
The later codes need an array, rather than an string. So init devlist
as an array to fix this problem.
