From 5e5801888d6ee3cfad07626355c337aa6d403cab Mon Sep 17 00:00:00 2001 From: Saurav Kashyap Date: Wed, 10 Jul 2024 22:40:50 +0530 Subject: [PATCH] scsi: qla2xxx: Return ENOBUFS if sg_cnt is more than one for ELS cmds commit ce2065c4cc4f05635413f63f6dc038d7d4842e31 upstream. Firmware only supports single DSDs in ELS Pass-through IOCB (0x53h), sg cnt is decided by the SCSI ML. User is not aware of the cause of an acutal error. Return the appropriate return code that will be decoded by API and application and proper error message will be displayed to user.
