commit 608ca5a60ee47b48fec210aeb7a795a64eb5dcee upstream. For dmabuf import users to be able to use the vaddr from another videobuf2-dma-sg source, the exporter needs to set a proper vaddr on vb2_dma_sg_dmabuf_ops_vmap callback. This patch adds vmap on map if buf->vaddr was not set.

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.
