Subject: [PATCH] thunderbolt: Add DP IN added last in the head of the list of
DP resources
Git-commit: 274baf695b08d34230253a792fcb3d6790040ab6
References: jsc#PED-6054
Patch-mainline: v6.7-rc1
If DP IN on device router exist, position it at the beginning of the DP
resources list, so that it is used before DP IN on host router. This way
external GPU will be prioritized when pairing DP IN and DP OUT for
DisplayPort tunnel setup.
