commit665636b294upstream. Fixes the signedness bug returning '(-22)' on the return type by removing the sanity checker in rockchip_ddrclk_get_parent(). The function should return and unsigned value only and it's safe to remove the sanity checker as the core functions that call get_parent like clk_core_get_parent_by_index already ensures the validity of the clk index returned (index >= core->num_parents).

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.
