Andrey Ryabinin 05c41f926f drm/i915: fix use-after-free in page_flip_completed() 
page_flip_completed() dereferences 'work' variable after executing
queue_work(). This is not safe as the 'work' item might be already freed
by queued work:

    BUG: KASAN: use-after-free in page_flip_completed+0x3ff/0x490 at addr ffff8803dc010f90

Move queue_work() after	trace_i915_flip_complete() to fix this.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
