The struct atomisp_overlay contains overlay_start_x and overlay_start_y fields. Instead of copying the value of the overlay_start_x field between the two structs, the value of the overlay_start_y field of the compat struct was copied to the overlay_start_x field of the 64-bit kernel struct in get operation and back in put. The overlay_start_x field value was not copied from or to the user space struct. Fix this so that the value of overlay_start_x is copied to overlay_start_x and the value of overlay_start_y is copied to overlay_start_y. Also do copy blend_overlay_perc_u field only once.

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.
