Zenghui Yu 18e65173fe kselftests: dmabuf-heaps: Ensure the driver name is null-terminated
[ Upstream commit 291e4baf70019f17a81b7b47aeb186b27d222159 ]

Even if a vgem device is configured in, we will skip the import_vgem_fd()
test almost every time.

  TAP version 13
  1..11
  # Testing heap: system
  # =======================================
  # Testing allocation and importing:
  ok 1 # SKIP Could not open vgem -1

The problem is that we use the DRM_IOCTL_VERSION ioctl to query the driver
version information but leave the name field a non-null-terminated string.
Terminate it properly to actually test against the vgem device.

While at it, let's check the length of the driver name is exactly 4 bytes
and return early otherwise (in case there is a name like "vgemfoo" that
gets converted to "vgem\0" unexpectedly).

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.
