[ Upstream commit bd54ccc0f147019dac38e7841876a7415459b875 ]
The mtk_clk_register_pll_ops() currently frees the "pll" parameter.
The function has two callers, mtk_clk_register_pll() and
mtk_clk_register_pllfh(). The first one, the _pll() function relies on
the free, but for the second _pllfh() function it causes a double free
bug.
Really the frees should be done in the caller because that's where
the allocation is.

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.
