[PATCH v3 4/7] HID: lenovo: Remove lenovo_led_brightness_get()
From: Hans de Goede <hidden>

The led_classdev already contains a cached value of the last set brightness, the brightness_get callback is only meant for LED drivers which can read back the actual / current brightness from the hardware. Since lenovo_led_brightness_get() just returns the last set value it does not add any functionality, so we can just remove it.
