If hci_register_dev() returns an error in hci_uart_init_work() then the HCI_UART_REGISTERED bit gets erroneously set due to a missing return statement. Therefore, add the missing return statement. The consequence of the missing return is that the HCI UART is not registered but HCI_UART_REGISTERED is set which allows the code to think that hu->hdev is safe to access but hu->hdev has been freed so could lead to a crash.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
