Arnd Bergmann 2980c03e1f media: staging: media: davinci_vpfe: fix large stack usage with clang
clang is unable to optimize the isif_ioctl() in the same way that
gcc does, as it fails to prove that the local copy of
the 'struct vpfe_isif_raw_config' argument is unnecessary:

drivers/staging/media/davinci_vpfe/dm365_isif.c:622:13: error: stack frame size of 1344 bytes in function 'isif_ioctl' [-Werror,-Wframe-larger-than=]

Marking it as 'const' while passing the data down clearly shows us that
the copy is never modified, and we can skip copying it entirely, which
reduces the stack usage to just eight bytes.

README

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.
