thinkpad-acpi: enhanced debugging messages for rfkill subdrivers
Enhance debugging messages for all rfkill subdrivers in thinkpad-acpi. Also, log a warning if the deprecated sysfs attributes are in use. These attributes are going to be removed sometime in 2010. There is an user-visible side-effect: we now coalesce attempts to enable/disable bluetooth or WWAN in the procfs interface, instead of hammering the firmware with multiple requests.
