Subject[PATCH 3/4] backlight: lcd: call put_device if device_register fails
Date
Currently we kfree the container of the device which failed to register.
This is wrong as the last reference is not given up with a put_device
call. Also, now that we have put_device() callen, we no longer need
the kfree as the new_ld->dev.release function will take care of kfreeing
the associated memory.
