From 34d96c0dedbfbba50349dcc76546a86ad59a0789 Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Mon, 16 Nov 2015 20:16:46 +0530 Subject: [PATCH] staging: unisys: return error value directly In case of error we are jumping to err_del_scsipending_ent and always returning SCSI_MLQUEUE_DEVICE_BUSY from error path. We donot need a variable to return a fixed error value, it can be returned directly.
