Subject: [PATCH] thunderbolt: Do not overwrite error code when domain adding
fails
Git-commit: 68a7a2ace13156b8a3d8cd6cceab6c30b52e2923
Patch-mainline: v4.17
References: FATE#324324
If the Thunderbolt domain adding fails for some reason we currently
always return -EIO instead of the real error code. To make debugging
easier return the actual error code instead.
