Rob Clark d60ec2e702 drm/msm: fix handling of cmdstream offset
[ Upstream commit 47e7f506ee ]

Userspace hasn't used submit cmds with submit_offset != 0 for a while,
but this starts cropping up again with cmdstream sub-buffer-allocation
in libdrm_freedreno.

Doesn't do much good to increment the buf ptr before assigning it.

Fixes: 78b8e5b847 drm/msm: dump a rd GPUADDR header for all buffers in the command

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.
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.
