Tom Rix a8cebb4a59 ALSA: asihpi: fix iounmap in error handler
[ Upstream commit 472eb39103e885f302fd8fd6eff104fcf5503f1b ]

clang static analysis flags this problem
hpioctl.c:513:7: warning: Branch condition evaluates to
  a garbage value
                if (pci.ap_mem_base[idx]) {
                    ^~~~~~~~~~~~~~~~~~~~

If there is a failure in the middle of the memory space loop,
only some of the memory spaces need to be cleaned up.

At the error handler, idx holds the number of successful
memory spaces mapped.  So rework the handler loop to use the
old idx.

There is a second problem, the memory space loop conditionally
iomaps()/sets the mem_base so it is necessay to initize pci.

README

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.
