[ Upstream commit255e51da15] In the case where fw_getenv returns an error when fetching values for ememsizea and memsize then variable phys_memsize is not assigned a variable and will be uninitialized on a zero check of phys_memsize. Fix this by initializing phys_memsize to zero. Cleans up cppcheck error: arch/mips/generic/yamon-dt.c:100:7: error: Uninitialized variable: phys_memsize [uninitvar] Fixes:f41d2430bb("MIPS: generic/yamon-dt: Support > 256MB of RAM") Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
