T.J. Mercier 8e1ffb2579 drm/syncobj: Fix syncobj leak in drm_syncobj_eventfd_ioctl
commit 8c7c44be57672e1474bf15a451011c291e85fda4 upstream.

A syncobj reference is taken in drm_syncobj_find, but not released if
eventfd_ctx_fdget or kzalloc fails. Put the reference in these error
paths.

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.
