Subject: [PATCH v2 04/30] HID: wacom: untie leds from inputs
Date: Wed, 13 Jul 2016 18:05:51 +0200	[thread overview]
Message-ID: <1468425977-4819-5-git-send-email-benjamin.tissoires@redhat.com> (raw)
In-Reply-To: <1468425977-4819-1-git-send-email-benjamin.tissoires@redhat.com>

Like remotes, LEDs should be handled by themself, not magically behind
the inputs as they have a complete different life.
