clk: sifive: allocate sufficient memory for struct __prci_data
The (struct __prci_data).hw_clks.hws is an array with dynamic elements.
Using struct_size(pd, hw_clks.hws, ARRAY_SIZE(__prci_init_clocks))
instead of sizeof(*pd) to get the correct memory size of
struct __prci_data for sifive/fu540-prci. After applying this
modifications, the kernel runs smoothly with CONFIG_SLAB_FREELIST_RANDOM
enabled on the HiFive unleashed board.

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.
