ACPI: thinkpad-acpi: update brightness sysfs interface support
Update the brightness sysfs interface (done through the backlight class) to be in line with the rest of the thinkpad-acpi driver. This renames the incorrect, un-obvious, and clash-prone name of "ibm" for the backlight device to a much more fitting and descriptive "thinkpad_screen". This is something I wanted to do for quite a while... Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Len Brown <len.brown@intel.com>
