[ Upstream commit5901eda2ed] In __of_find_n_match_cpu_property(), checking the variable ac for 0 won't prevent a possible overflow when multiplying it by sizeof(*cell). Besides, of_read_number() (called in the *for* loop) can't return correct result if that variable (which equals the #address-cells prop's value) exceeds 2, so additionally checking for that seems logical... Found by Linux Verification Center (linuxtesting.org) with the Svace static analysis tool.

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.
