From 1c3adf0de1db86cf354dcb1a2dd1184e5e63a50a Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Tue, 15 Feb 2022 07:03:08 -0800 Subject: [PATCH] nvme: explicitly set non-error for directives Stream directives is an optional feature. It is not an error if a controller doesn't support as many as the kernel can optionally use. Explicitly set the non-error return value on this condition with a comment explaining why. Note, the return value was already 0 in this condition, so the setting is redundant. This patch should just silence bots that falsely believe the condition contains an error omission.
