For the commands COMMAND_RAISE_LEGACY_IRQ, COMMAND_RAISE_MSI_IRQ and COMMAND_RAISE_MSIX_IRQ, the function pci_epf_test_cmd_handler() sets the STATUS_IRQ_RAISED status flag and calls the epc function pci_epc_raise_irq() directly. However, this is also exactly what the pci_epf_test_raise_irq() function does. Avoid duplicating these operations by directly using pci_epf_test_raise_irq() for the IRQ test commands. It is OK to do so as the host side endpoint test driver always set the correct IRQ type for the IRQ test commands. At the same time, move the IRQ number check done for the COMMAND_RAISE_MSI_IRQ and COMMAND_RAISE_MSIX_IRQ commands to pci_epf_test_raise_irq(), to also check the IRQ number requested by the host for other test commands. This significantly simplifies pci_epf_test_cmd_handler().

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.
