From mboxrd@z Thu Jan 1 00:00:00 1970 From: wens@csie.org (Chen-Yu Tsai) Date: Fri, 17 Feb 2017 11:13:29 +0800 Subject: [PATCH 6/7] drm/sun4i: Save newly created layer in layers array in sun4i_layers_init In-Reply-To: <20170217031330.14087-1-wens@csie.org> References: <20170217031330.14087-1-wens@csie.org> Message-ID: <20170217031330.14087-7-wens@csie.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org sun4i_layers_init allocates an array to store pointers to newly created layers returned by sun4i_layer_init_one(), but fails to actually store them. But it actually returns the empty array to unsuspecting users. Save the pointers in the array, so that they may be used later.
