This patch removes the error checking for debugfs_create_dir in adm1266.c. This is because the debugfs_create_dir() does not return NULL but an ERR_PTR after an error. The DebugFS kernel API is developed in a way that the caller can safely ignore the errors that occur during the creation of DebugFS nodes.The debugfs Api handles it gracefully. The check is unnecessary.
