Subject: [PATCH stable 5.8 05/25] chelsio/chtls: fix panic when server is on ipv6
From: Vinay Kumar Yadav <vinay.yadav@xxxxxxxxxxx>
[ Upstream commit 86cdf9ca4409d997a391103e480b3f77b7ccc19b ]
Netdev is filled in egress_dev when connection is established,
If connection is closed before establishment, then egress_dev
is NULL, Fix it using ip_dev_find() rather then extracting from
egress_dev.
Fixes: 6abde0b24122 ("crypto/chtls: IPv6 support for inline TLS")
