Date: Fri, 17 Jun 2011 20:25:12 +0400 From: Pavel Shved <shved@...ras.ru> To: Paul Mundt <lethal@...ux-sh.org> Cc: Pavel Shved <shved@...ras.ru>, linux-fbdev@...r.kernel.org, linux-kernel@...r.kernel.org, ldv-project@...ras.ru Subject: [PATCH] hecubafb: add module_put on error path in hecubafb_probe() In hecubafb_probe(), after a successful try_module_get, vzalloc may fail and make the hecubafb_probe return, but the module is not put on this error path. This patch adds an exit point that calls module_put in such situation. Found by Linux Driver Verification project (linuxtesting.org).
