Protect the access to driver and timeline name which otherwise could be freed as dma-fence exported is signalling fences. This prepares the code for incoming dma-fence API changes which will start asserting these accesses are done from a RCU locked section. Now that the safe access is handled in the dma-fence API, the external callers such as sync_file, and our internal code paths, we can drop the similar protection from i915_fence_get_timeline_name(). This prepares the code for incoming dma-fence API changes which will start asserting these accesses are done from a RCU locked section.

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 reStructuredText 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.
