stable inclusion from stable-v6.6.13 commit e1d391310724e0353ed302e57cf55f1bc056b81c bugzilla: https://gitee.com/openeuler/kernel/issues/I99TJK
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 3d1dc8b1030df8ca0fdfd4905c88ee10db943bf8 ]
When the HDMI is not present due to disabled display support we will use dummy codec and the HDMI routes will refer to non existent DAPM widgets.
Trim the route list from the HDMI routes to be able to probe the card even if the HDMI dais are not registered.
