Subject: [PATCH v2 31/32] util: Always return -1 on error in sock_l4()
Date: Thu, 17 Nov 2022 16:59:07 +1100	[thread overview]
Message-ID: <20221117055908.2782981-32-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20221117055908.2782981-1-david@gibson.dropbear.id.au>

According to its doc comments, sock_l4() returns -1 on error.  It does,
except in one case where it returns -EIO.  Fix this inconsistency to match
the docs and always return -1.
