From: Dan Carpenter Date: Fri, 23 Jun 2017 07:02:00 +0000 (+0300) Subject: scsi: bnx2i: missing error code in bnx2i_ep_connect() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1d32a62c74b3bcb69822b0f4745af5410cfec3a7;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git scsi: bnx2i: missing error code in bnx2i_ep_connect() If bnx2i_map_ep_dbell_regs() then we accidentally return NULL instead of an error pointer. It results in a NULL dereference in iscsi_if_ep_connect(). Fixes: cf4e6363859d ("[SCSI] bnx2i: Add bnx2i iSCSI driver.")
