[ Upstream commit cf28aee292e102740e49f74385b4b89c00050763 ]
There is a new firmware for the Steam Controller with support for BLE
connections. When using such a device with a wired connection, it
reboots itself every 10 seconds unless an application has opened it.
Doing hid_hw_open() unconditionally on probe fixes the issue, and the
code becomes simpler.
