Recent Vaios (C, AR, N, FE) need some special initialization
sequence to enable Fn keys interrupts through the Embedded
Controller. Moreover Fn keys have to be decoded internally
using ACPI methods to get the key code.
Thus a new DMI table to add SNC init time callbacks and new
mappings for model-specific key code to generic sony-laptop
code have been added.

Both the SNC and SPIC device drivers will create attributes and thus
there's the need to have an internal usage count to avoid

Remove uneeded owner field from backlight_properties structure.

Nothing uses it and it is unlikely that it will ever be used. The

Replace sony_acpi_value.{min,max} with a callback function that allows

  Even though the devices claimed by sony_acpi.c can not be hot-plugged, the
  driver registration infrastructure allows the .add() and .remove() methods
  to be called at any time while the driver is registered.  So remove __init
  and __exit from them.
