Instead of ignoring errors returned by devm_clk_get() and manually enabling the clk for the whole lifetime of the bound device, use devm_clk_get_optional_enabled(). This is simpler and also more correct as it doesn't ignore errors. This is also more correct because now the call to clk_disable_unprepare() can be dropped from xgene_rng_remove() which happened while the hwrn device was still registered. With the devm callback disabling the clk happens correctly only after devm_hwrng_register() is undone. As a result struct xgene_rng_dev::clk is only used in xgene_rng_probe, and so the struct member can be replaced by a local variable.

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.
