[PATCH 08/19] platform/x86: lenovo-yogabook: Add dev local variable to probe()

[Hans de Goede <hdegoede@redhat.com>]

Add a "struct device *dev" local variable to probe().

This is a preparation patch for making lenovo-yogabook-wmi also work
on the Android version of the Yoga Book 1 which does not have a WMI
interface to deal with toggling the keyboard half between
touch-keyboard and wacom-digitizer mode.
