Panel Taal driver uses the string "taal" to register for a backlight device. This causes backlight_device_register() to fail when a second taal panel is added. Use dev_name(&dssdev->dev) as a parameter instead of the string. Note: This will break backlight related sysfs commands. Use the name as generated by the DSS2 driver, in the form "displayi", which represents the ith registered display device.
