Subject: [PATCH 2/2] staging: unisys: return error value directly
Date: Mon, 16 Nov 2015 20:16:46 +0530	[thread overview]
Message-ID: <1447685206-21163-2-git-send-email-sudipm.mukherjee@gmail.com> (raw)
In-Reply-To: <1447685206-21163-1-git-send-email-sudipm.mukherjee@gmail.com>

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.
