Since commita6d7514b14("tty: serial: lpuart: add a more accurate baud rate calculation method") the baud rate is now calculated inside the lpuart32_serial_setbrg() function, so we no longer need to read the UARTBAUD register inside lpuart32_set_termios(). The 'bd' variable can be simply removed. This fixes the following build warning with W=1: drivers/tty/serial/fsl_lpuart.c: In function 'lpuart32_set_termios': drivers/tty/serial/fsl_lpuart.c:1652:32: warning: variable 'bd' set but not used [-Wunused-but-set-variable] Fixes:a6d7514b14("tty: serial: lpuart: add a more accurate baud rate calculation method") Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.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.
