During build testing, I ran into a warning in a driver that I had written myself at some point: drivers/tty/serial/8250/8250_of.c: In function 'of_platform_serial_probe': drivers/tty/serial/8250/8250_of.c:233:1: error: the frame size of 1200 bytes is larger than 1152 bytes [-Werror=frame-larger-than=] This is harmless by itself, but it shows two other problems in the driver: - It still tries to be generic enough to handle all kinds of serial ports, where in reality the driver has been 8250-only for a while, and every other uart has its own DT support - As a result of that generalization, we keep two copies of 'struct uart_port' on the stack during probe(). This is completely unnessary. Removing the last code dealing with unsupported port_type values solves both problems nicely, and reduces the stack size.

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.
