Subject: [net-next v0 05/14] net/mlx5: SF, silence an uninitialized variable warning
Date: Thu, 2 Dec 2021 16:56:13 -0800 [thread overview]
Message-ID: <20211203005622.183325-6-saeed@kernel.org> (raw)
In-Reply-To: <20211203005622.183325-1-saeed@kernel.org>
From: Dan Carpenter <dan.carpenter@oracle.com>
This code sometimes calls mlx5_sf_hw_table_hwc_init() when "ext_base_id"
is uninitialized. It's not used on that path, but it generates a static
checker warning to pass uninitialized variables to another function.
It may also generate runtime UBSan warnings depending on if the
mlx5_sf_hw_table_hwc_init() function is inlined or not.
