Subject: [PATCH v3 1/7] Input: add input_device_enabled()
Date: Fri, 5 Jun 2020 19:33:29 +0200 [thread overview]
Message-ID: <20200605173335.13753-2-andrzej.p@collabora.com> (raw)
In-Reply-To: <20200605173335.13753-1-andrzej.p-ZGY8ohtN/8qB+jHODAdFcQ@public.gmane.org>
A helper function for drivers to decide if the device is used or not.
A lockdep check is introduced as inspecting ->users should be done under
input device's mutex.
Signed-off-by: Andrzej Pietrasiewicz <andrzej.p-ZGY8ohtN/8qB+jHODAdFcQ@public.gmane.org>
