[PATCH AUTOSEL 5.13 28/29] NTB: perf: Fix an error code in perf_setup_inbuf()

From: Sasha Levin <sashal@kernel.org>
Date: 2021-09-11 13:16:51

Subsystem: ntb driver core, the rest · Maintainers: Jon Mason, Dave Jiang, Allen Hubbe, Linus Torvalds

From: Yang Li <redacted>

[ Upstream commit 0097ae5f7af5684f961a5f803ff7ad3e6f933668 ]

When the function IS_ALIGNED() returns false, the value of ret is 0.
So, we set ret to -EINVAL to indicate this error.

Clean up smatch warning:
drivers/ntb/test/ntb_perf.c:602 perf_setup_inbuf() warn: missing error
code 'ret'.
