[PATCH 5.13 367/800] nvme-tcp: fix error codes in nvme_tcp_setup_ctrl()

From: Greg Kroah-Hartman
Date: Mon Jul 12 2021 - 04:34:05 EST


From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit 522af60cb2f8e3658bda1902fb7f200dcf888a5c ]

These error paths currently return success but they should return
-EOPNOTSUPP.

Fixes: 73ffcefcfca0 ("nvme-tcp: check sgl supported by target")
Fixes: 3f2304f8c6d6 ("nvme-tcp: add NVMe over TCP host driver")
