Subject: [PATCH AUTOSEL 5.10 24/25] NTB: perf: Fix an error code in perf_setup_inbuf()
Date: Sat, 11 Sep 2021 09:13:11 -0400 [thread overview]
Message-ID: <20210911131312.285225-24-sashal@kernel.org> (raw)
In-Reply-To: <20210911131312.285225-1-sashal@kernel.org>
From: Yang Li <yang.lee@linux.alibaba.com>
[ 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'.
