The kdoc for pci_epc_set_msix() says: "Invoke to set the required number of MSI-X interrupts." The kdoc for the callback pci_epc_ops->set_msix() says: "ops to set the requested number of MSI-X interrupts in the MSI-X capability register" pci_epc_ops::set_msix() does however expect the parameter 'interrupts' to be in the encoding as defined by the Table Size field. Nowhere in the kdoc does it say that the number of interrupts should be in Table Size encoding. It is very confusing that the API pci_epc_set_msix() and the callback function pci_epc_ops::set_msix() both take a parameter named 'interrupts', but they expect completely different encodings. Clean up the API and the callback function to have the same semantics, i.e. the parameter represents the number of interrupts, regardless of the internal encoding of that value. Also rename the parameter 'interrupts' to 'nr_irqs', in both the wrapper function and the callback function, such that the name is unambiguous.

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 reStructuredText 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.
