Hi! +The current brightness is found by reading a single byte from the character +device. Values are unsigned: 0 to 255. Reading does not block and always returns +the most recent brightness value. The device node can also be polled to notify +when the brightness value changes. What is going on there? We have O_NONBLOCK, user should be able to select if he wants blocking behaviour or not. And yes, there's interface for creating a LED, but not one for deleting it? And... how is it going to work with multiple LEDs? Userspace gets single bytes with brightness. How does it know to which LED the brightness belongs?
