Gcc 7.1 complains that: drivers/media/platform/mtk-vcodec/mtk_vcodec_dec.c: In function 'mtk_vdec_pic_info_update': drivers/media/platform/mtk-vcodec/mtk_vcodec_dec.c:284:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable] int ret; ^~~ Indeed, if debug is disabled, "ret" is never used. The best fix for it seems to make the fuction to return an error code. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.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.
