From b3ed02cc8ca8225b9a86d54baea1d3d958e11718 Mon Sep 17 00:00:00 2001 From: Tomas Henzl Date: Fri, 24 Mar 2023 16:01:34 +0100 Subject: [PATCH] scsi: megaraid_sas: Fix crash after a double completion [ Upstream commit 2309df27111a51734cb9240b4d3c25f2f3c6ab06 ] When a physical disk is attached directly "without JBOD MAP support" (see megasas_get_tm_devhandle()) then there is no real error handling in the driver. Return FAILED instead of SUCCESS.
