commitbbeddf52ad("printk: move braille console support into separate braille.[ch] files") introduced _braille_console_setup() to outline the braille initialization code. There was however some confusion over the value it was supposed to return. commit2cfe6c4ac7("printk: Fix return of braille_register_console()") tried to fix it but failed to. This fixes and documents the returned value according to the use in printk.c: non-zero return means a parsing error, and thus this console configuration should be ignored.

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.
