->size field in struct qaic_bo stores user requested buffer size for allocate path or size of the dmabuf(PRIME). Now for allocate path driver allocates a BO of size which is PAGE_SIZE aligned, this size is already stored in base BO structure (struct drm_gem_object). So difference is ->size of struct qaic_bo stores the raw value coming from user and ->size in struct drm_gem_object stores the PAGE_SZIE aligned size. Do not use ->size from struct qaic_bo for any validation or operation instead use ->size from struct drm_gem_object since we already have allocated that much memory then why not use it. Only validate if user is trying to use more then the BO size. This make the driver more flexible. After this change ->size field of struct qaic_bo becomes redundant. Remove it.

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.
