Date: Fri, 17 Feb 2017 11:13:27 +0800 From: Chen-Yu Tsai <wens@...e.org> To: Maxime Ripard <maxime.ripard@...e-electrons.com>, David Airlie <airlied@...ux.ie> Cc: Chen-Yu Tsai <wens@...e.org>, dri-devel@...ts.freedesktop.org, linux-sunxi@...glegroups.com, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [PATCH 4/7] drm/sun4i: Fix kcalloc element size in sun4i_layers_init In sun4i_layers_init we are allocating an array of pointers to struct sun4i_layer: layers = devm_kcalloc(drm->dev, ARRAY_SIZE(sun4i_backend_planes), sizeof(**layers), GFP_KERNEL); The element size should be the size of an individual element of the array. Change it to sizeof(*layers) to avoid wasting a lot of memory.
