Hi all,
Here are a couple of changes which have been in my TODO list some time
already but have not had time to make a proper patch out of them until now.
The only change to the previous version is that I realized it could be
useful for users to see the actual connected devices (including their name
which is read from DROM) printed to the system log. Hence the patch 2/4.
Mika Westerberg (4):
thunderbolt: Make the driver less verbose
thunderbolt: Print connected devices
thunderbolt: Convert rest of the driver files to use SPDX identifier
thunderbolt: Add Intel as copyright holder

This information is not useful for ordinary users and might even annoy some. For this reason convert most of the logs at info level to happen at debug level instead. The nice output formatting is untouched. Logging can be easily re-enabled by passing "thunderbolt.dyndbg" in the kernel command line (or using the corresponding control file runtime).
