The value of return variable ret is 0 on some error paths, for example, when pci_resource_start() returns a NULL pointer. 0 means no error in this context, which is contrary to the fact. This patch fixes the bug. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=189011 Signed-off-by: Pan Bian <bianpan2016@163.com> 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.
