Subject: thunderbolt: Do not overwrite error code when domain adding fails
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=68a7a2ace13156b8a3d8cd6cceab6c30b52e2923;p=linux.git

thunderbolt: Do not overwrite error code when domain adding fails

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.
