Subject: drm_fb_helper.c:1247:1-8: alloc with no test
Date: Fri, 17 Aug 2012 03:27:42 +0000 [thread overview]
Message-ID: <20120817032742.GB26867@localhost> (raw)
Hi Daniel,
FYI, here is a potential problem on memory allocation failure, caught by coccinelle:
+ drivers/gpu/drm/drm_fb_helper.c:1247:1-8: alloc with no test, possible model on line 1252
vim +1247 drivers/gpu/drm/drm_fb_helper.c
1244 sizeof(struct drm_fb_helper_crtc *), GFP_KERNEL);
1245 modes = kcalloc(dev->mode_config.num_connector,
1246 sizeof(struct drm_display_mode *), GFP_KERNEL);
> 1247 enabled = kcalloc(dev->mode_config.num_connector,
1248 sizeof(bool), GFP_KERNEL);
1249
1250 drm_enable_connectors(fb_helper, enabled);
