[PATCH 5.18 097/181] Revert "net/tls: fix tls_sk_proto_close executed repeatedly"

[Greg Kroah-Hartman]

From: Jakub Kicinski <kuba@xxxxxxxxxx>

[ Upstream commit 1b205d948fbb06a7613d87dcea0ff5fd8a08ed91 ]

This reverts commit 69135c572d1f84261a6de2a1268513a7e71753e2.

This commit was just papering over the issue, ULP should not
get ->update() called with its own sk_prot. Each ULP would
need to add this check.
