The request_t 'handle' member is 32-bits wide, hence use wrt_reg_dword().
Change the cast in the wrt_reg_byte() call to make it clear that a regular
pointer is casted to an __iomem pointer.
Note: 'pkt' points to I/O memory for the qlafx00 adapter family and to
coherent memory for all other adapter families.
This patch fixes the following Coverity complaint:
CID 358864 (#1 of 1): Reliance on integer endianness (INCOMPATIBLE_CAST)
incompatible_cast: Pointer &pkt->handle points to an object whose effective
type is unsigned int (32 bits, unsigned) but is dereferenced as a narrower
unsigned short (16 bits, unsigned). This may lead to unexpected results
depending on machine endianness.

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.
