The warnings are: drivers/auxdisplay/img-ascii-lcd.c: warning: 'err' may be used uninitialized in this function [-Wuninitialized] At lines 109 and 207. Reported by Geert using the build service several times, e.g.: https://lkml.org/lkml/2018/2/19/303 They are two false positives, since num_chars > 0 in the three present configurations (boston, malta, sead3). Initialize to 0 in order to silence the warning. Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Paul Burton <paul.burton@mips.com> Signed-off-by: Miguel Ojeda <miguel.ojeda.sandonis@gmail.com>
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.
