From bca1c43cb2dbe4212aea0793bfd91aeb4c2d184d Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Wed, 4 Dec 2019 09:17:41 -0700 Subject: null_blk: remove unused variable warning on !CONFIG_BLK_DEV_ZONED If BLK_DEV_ZONED isn't set, 'ret' isn't used. This makes gcc complain, rightfully. Move ret where it is used.
