Chen Zhongjin f3f65c4177 vme: Fix error not catched in fake_init()
[ Upstream commit 7bef797d707f1744f71156b21d41e3b8c946631f ]

In fake_init(), __root_device_register() is possible to fail but it's
ignored, which can cause unregistering vme_root fail when exit.

 general protection fault,
 probably for non-canonical address 0xdffffc000000008c
 KASAN: null-ptr-deref in range [0x0000000000000460-0x0000000000000467]
 RIP: 0010:root_device_unregister+0x26/0x60
 Call Trace:
  <TASK>
  __x64_sys_delete_module+0x34f/0x540
  do_syscall_64+0x38/0x90
  entry_SYSCALL_64_after_hwframe+0x63/0xcd

Return error when __root_device_register() fails.

README

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.
