This adds support to ftdi_sio for the Infineon TriBoard TC2X7 engineering board for first-generation Aurix SoCs with Tricore CPUs. Mere addition of the device IDs does the job.

USB: serial: fix potential NULL-dereference at probe 2016-11-10T15:38:49+00:00 Johan Hovold johan@kernel.org 2016-10-21T10:56:27+00:00 e8bf726705bd482371f5ba94274e19237717e1a1 commit 126d26f66d9890a69158812a6caa248c05359daa upstream. Make sure we have at least one port before attempting to register a console. Currently, at least one driver binds to a "dummy" interface and requests zero ports for it. Should such an interface also lack endpoints, we get a NULL-deref during probe.
