[ Upstream commit bc4071aafcf4d0535ee423b69167696d6c03207d ] aspeed_create_fan() reads a pwm_port value using of_property_read_u32(). If pwm_port will be more than ARRAY_SIZE(pwm_port_params), there will be a buffer overflow in aspeed_create_pwm_port()->aspeed_set_pwm_port_enable(). The patch fixes the potential buffer overflow.

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.
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.
