etnaviv_iommuv2_dump_size(..) returns the number of PTE * SZ_4K but
etnaviv_iommuv2_dump(..) increments buf pointer even if there is no PTE.
This results in a bad buf pointer which gets used for memcpy(..), when
copying the MMU state in the coredump buffer.
Fixes: afb7b3b1de ("drm/etnaviv: implement IOMMUv2 translation")

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.
