From 47742bde281b2920aae8bb82ed2d61d890aa4f56 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 9 May 2020 13:04:08 +0300 Subject: scsi: scsi_debug: Fix an error handling bug in sdeb_zbc_model_str() This test is checking the wrong variable. It should be testing "res". The "sdeb_zbc_model" variable is an enum (unsigned in this situation) and we never assign negative values to it.
