Subject: [PATCH net-next 01/12] netfilter: nft_inner: fix IS_ERR() vs NULL check
Date: Sun, 11 Dec 2022 11:11:53 +0100 [thread overview]
Message-ID: <20221211101204.1751-2-pablo@netfilter.org> (raw)
In-Reply-To: <20221211101204.1751-1-pablo@netfilter.org>
From: Dan Carpenter <error27@gmail.com>
The __nft_expr_type_get() function returns NULL on error. It never
returns error pointers.
Fixes: 3a07327d10a0 ("netfilter: nft_inner: support for inner tunnel header matching")
