The function pci_epf_test_cmd_handler() uses the register BAR address as a pointer to a struct pci_epf_test_reg to determine the command sent by the host and to execute the test function accordingly. There is no need for doing this assignment again in each of the read, write and copy test functions. We can simply pass the reg pointer as an argument to the functions pci_epf_test_write(), pci_epf_test_read() and pci_epf_test_copy().

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.
