Dafna Hirschfeld 5f028c51a7 media: staging: rkisp1: capture: remove support to userptr memory
VB2_USERPTR support doesn't make sense for drivers based on
vb2_dma_contig, so just drop it.

Otherwise, queues using vb2_dma_contig_memops causes v4l2-compliance
to fail for VB2_USERPTR mode, due to buffer misalignment.

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.
