Structs battery_file, acpi_dock_ops, file_operations,
thermal_cooling_device_ops, thermal_zone_device_ops, kernel_param_ops
are not changed in runtime. It is safe to make them const.
register_hotplug_dock_device() was altered to take const "ops" argument
to respect acpi_dock_ops' const notion.

Len, I think it can be applied as a single patch to acpi tree as the
only non-acpi thing is acpi_dock_ops in ata/ and pci/, which is really
trivial.
