Ensure that HCI_UART_PROTO_READY is cleared before close(hu) is called which closes the Data Link protocol layer. Therefore, add the missing bit clear of HCI_UART_PROTO_READY to hci_uart_init_work() so that the flag is cleared when hci_register_dev fails. Without the fix, the functions of the Data Link protocol layer could potentially be accessed after that layer has been closed. This could lead to a crash as memory would have been freed in that layer. Signed-off-by: Dean Jenkins <Dean_Jenkins@mentor.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
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.
