Hans de Goede ffe3dc5aca media: atomisp: Fix eed1_8 code assigning signed values to an unsigned variable
ia_css_eed1_8_vmem_encode() is assigning values with a range of -8192 -
8191 to e_dew_enh_y and e_dew_enh_a both of which are of the VMEM_ARRAY
type which maps to u16.

This causes the following smatch warnings:

drivers/staging/media/atomisp/pci/isp/kernels/eed1_8/ia_css_eed1_8.host.c: drivers/staging/media/atomisp/pci/isp/kernels/eed1_8/ia_css_eed1_8.host.c:177 ia_css_eed1_8_vmem_encode() warn: assigning (-8192) to unsigned variable 'to->e_dew_enh_y[0][base + j]'
drivers/staging/media/atomisp/pci/isp/kernels/eed1_8/ia_css_eed1_8.host.c: drivers/staging/media/atomisp/pci/isp/kernels/eed1_8/ia_css_eed1_8.host.c:182 ia_css_eed1_8_vmem_encode() warn: assigning (-8192) to unsigned variable 'to->e_dew_enh_a[0][base + j]'

Convert the e_dew_enh_y and e_dew_enh_a arrays to a new SVMEM_ARRAY type
which maps to s16 to fix this.

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 reStructuredText 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.
