From a59d6293e5372d7c35212932e083e2a541151eff Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Wed, 23 May 2012 15:13:07 +0200 Subject: [PATCH] debugfs: change parameter check in debugfs_remove() functions The dentry parameter in debugfs_remove() and debugfs_remove_recursive() is checked being a NULL pointer. To make cleanup by callers easier this check is extended using the IS_ERR_OR_NULL macro instead because the debugfs_create_... functions can return a ERR_PTR() value.
