Subject: [PATCH v2 4/7] HID: lenovo: Remove lenovo_led_brightness_get()
Date: Sat, 20 Feb 2021 13:24:35 +0100 [thread overview]
Message-ID: <20210220122438.21857-5-hdegoede@redhat.com> (raw)
In-Reply-To: <20210220122438.21857-1-hdegoede@redhat.com>
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.
