From 319f83ac98d7afaabab84ce5281a819a358b9895 Mon Sep 17 00:00:00 2001 From: Yang Li Date: Mon, 7 Jun 2021 13:56:20 +0800 Subject: [PATCH] NTB: Fix an error code in ntb_msit_probe() When the value of nm->isr_ctx is false, the value of ret is 0. So, we set ret to -ENOMEM to indicate this error. Clean up smatch warning: drivers/ntb/test/ntb_msi_test.c:373 ntb_msit_probe() warn: missing error code 'ret'.
