[PATCH 2/3] platform/x86: wmi: add context argument to the probe function

[Mattias Jacobsson]

The struct wmi_device_id has a context pointer field, forward this
pointer as an argument to the probe function in struct wmi_driver.

Update existing users of the same probe function to accept this new
context argument.
