1a3e323907 sonypi: try to detect if sony-laptop has already taken one of the known ioports
Get the IO resources list in sony-laptop in the same order as listed
in sonypi and make sonypi check if one of those is already busy.
The sonypi check can be disabled by a module parameter in case the user
thinks we are plainly wrong (check_ioport=0).

dfcba20067 backlight: Remove unneeded owner field
Remove uneeded owner field from backlight_properties structure.

Nothing uses it and it is unlikely that it will ever be used. The
backlight class uses other means to ensure that nothing references
unloaded code.

Based on a patch from Dmitry Torokhov <dtor@insightbb.com>

156c221b72 sony-laptop: allow complex per-value input/output validation
Replace sony_acpi_value.{min,max} with a callback function that allows
more complex reasoning in accepting input and presenting output.

This allows consistency between the sony-laptop specific 'brightness_default'
and the backlight subsystem 0-based 'brightness'.
