Ondrej Zary 5bc9e2d43f ata: pata_parport: fix memory leaks
When ida_alloc() fails, "pi" is not freed although the misleading
comment says otherwise.
Move the ida_alloc() call up so we really don't have to free "pi" in
case of ida_alloc() failure.

Also move ida_free() call from pi_remove_one() to
pata_parport_dev_release(). It was dereferencing already freed dev
pointer.

Testing revealed leak even in non-failure case which was tracked down
to missing put_device() call after bus_find_device_by_name(). As a
result, pata_parport_dev_release() was never called.

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.
