Subject: [PATCH net-next 1/6] net: dcb: modify dcb_app_add to take list_head ptr as parameter

From: Daniel Machon <[email-masked]>
Date: Thu, 12 Jan 2023 21:15:49 +0100

In preparation to DCB rewrite. Modify dcb_app_add to take new struct
list_head * as parameter, to make the used list configurable. This is
done to allow reusing the function for adding rewrite entries to the
rewrite table, which is introduced in a later patch.
