The msm_gem_new_impl() function cleans up after itself so there is no
need to call drm_gem_object_put(). Conceptually, it does not make sense
to call a kref_put() function until after the reference counting has
been initialized which happens immediately after this call in the
drm_gem_(private_)object_init() functions.
In the msm_gem_import() function the "obj" pointer is uninitialized, so
it will lead to a crash.

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.
