Wolfgang Wallner 854901ccd4 gpio: Return -ENODEV if gpio_hog_lookup_name() is empty 
If CONFIG_GPIO_HOG is not set, then gpio_hog_lookup_name() is empty,
and thus does not initialize any of its parameters. It does still
return 0 though, and so any calling function might assume that the
parameters have been initialized successfully.

Change the return value to -ENODEV in this case, as the function
would in the case when CONFIG_GPIO_HOG is set but the gpio hog
could not be found.
