checkpatch.pl: Use of uninitialized value $str in split at ./scripts/checkpatch.pl line 1079.

Hi,

I've noticed that checkpatch prints an error in linux-next. This can
be reproduced via

./scripts/checkpatch.pl --strict --file net/batman-adv/bat_iv_ogm.c

This problem seems to be introduced by d369873d2f53 ("Merge branch
'akpm-current/current'") which is a merge of 6a6594aace5c ("Merge
remote-tracking branch 'nvdimm/libnvdimm-for-next'") and cdaa6aa1e90c
("kexec_file fixup"). But please check this because I am new to
git-bisect

Greetings
