commit4aa37c4637upstream. Recently, there's been some compat ioctl cleanup, in which large hardcoded lists were replaced with compat_ptr_ioctl. One of these changes involved removing the random.c hardcoded list entries and adding a compat ioctl function pointer to the random.c fops. In the process, urandom was forgotten about, so this commit fixes that oversight.

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.
