Deprecate pcim_iomap_table(). It returns a pointer to a table of ioremapped BARs, or NULL if it fails. This makes uses like this: addr = pcim_iomap_table(pdev)[0]; problematic because it causes a NULL pointer dereference on failure. Callers should use pcim_iomap() instead. Deprecate pcim_iomap_regions_request_all() because it is built on __pci_request_region() and is managed if pcim_enable_device() has been called, but unmanaged otherwise, which is prone to errors. Callers should either use pcim_iomap_regions() to request and map BARs, or use pcim_request_region() followed by pcim_iomap().

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.
