From: "Jason A. Donenfeld" <Jason@zx2c4.com>
commit 4aa37c463764052c68c5c430af2a67b5d784c1e0 upstream.
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.
