From 746b31a9d4e08240d267069bcf5084eb7e427ad7 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Thu, 17 Jan 2008 12:01:30 -0500 Subject: [PATCH] Input: psmouse - fix potential memory leak in psmouse_connect() If we successfully call input_register_device() in psmouse_connect() but sysfs_create_group() fails, we'll enter the error path without ever having called input_unregister_device() potentially leaking memory.
