Subject: [PATCH 07/10] leds: class: Use correct type for brightness_hw_changed field
Date: Sun, 18 Oct 2026 15:46:26 +0200 [thread overview]
Message-ID: <20261018135339.1109271-8-W_Armin@gmx.de> (raw)
In-Reply-To: <20261018135339.1109271-1-W_Armin@gmx.de>
Device drivers can supply a unsigned integer using
led_classdev_notify_brightness_hw_changed(), but the associated
field can only store signed integers, leading to issues for very
large brightness values.
Fix this by using the correct type for the brightness_hw_changed
field.
