Subject: [bug report] drm/komeda: Add writeback support
Date: Wed, 14 Aug 2019 17:09:30 +0300	[thread overview]
Message-ID: <20190814140930.GA31850@mwanda> (raw)

Hello james qian wang (Arm Technology China),

The patch 5d51f6c0da1b: "drm/komeda: Add writeback support" from May
23, 2019, leads to the following static checker warning:

	drivers/gpu/drm/arm/display/komeda/komeda_wb_connector.c:151 komeda_wb_connector_add()
	error: not allocating enough data 1592 vs 1584

drivers/gpu/drm/arm/display/komeda/komeda_wb_connector.c
   139  static int komeda_wb_connector_add(struct komeda_kms_dev *kms,
   140                                     struct komeda_crtc *kcrtc)
   141  {
   142          struct komeda_dev *mdev = kms->base.dev_private;
   143          struct komeda_wb_connector *kwb_conn;
   144          struct drm_writeback_connector *wb_conn;
   145          u32 *formats, n_formats = 0;
   146          int err;
   147  
   148          if (!kcrtc->master->wb_layer)
   149                  return 0;
   150  
   151          kwb_conn = kzalloc(sizeof(*wb_conn), GFP_KERNEL);
                                           ^^^^^^^
This should probably be "kwb_conn" with a k?

   152          if (!kwb_conn)
   153                  return -ENOMEM;
   154  
   155          kwb_conn->wb_layer = kcrtc->master->wb_layer;
   156  
   157          wb_conn = &kwb_conn->base;
   158          wb_conn->encoder.possible_crtcs = BIT(drm_crtc_index(&kcrtc->base));
   159  
   160          formats = komeda_get_layer_fourcc_list(&mdev->fmt_tbl,
   161                                                 kwb_conn->wb_layer->layer_type,
   162                                                 &n_formats);

regards,
dan carpenter
