Introduce the epc core helper function pci_epc_function_is_valid() to verify that an epc pointer, a physical function number and a virtual function number are all valid. This avoids repeating the code pattern: if (IS_ERR_OR_NULL(epc) || func_no >= epc->max_functions) return err; if (vfunc_no > 0 && (!epc->max_vfs || vfunc_no > epc->max_vfs[func_no])) return err; in many functions of the endpoint controller core code.

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.
