Subject: [PATCH 03/11] drm/sun4i: Add end of list element for sun4i_layers_init's returned list
Date: Thu, 23 Feb 2017 16:05:35 +0800 [thread overview]
Message-ID: <20170223080543.6659-4-wens@csie.org> (raw)
In-Reply-To: <20170223080543.6659-1-wens@csie.org>
The number of defined planes in sun4i_layer is unknown to other parts
of the sun4i drm driver. Since the return value of sun4i_layers_init
is a list of layers, make it return 1 more empty layer as an end of
list guard value.
