Brett Creeley 2bbf2b1c20 pds_core: Rework teardown/setup flow to be more common 
[ Upstream commit bc90fbe0c3 ]

Currently the teardown/setup flow for driver probe/remove is quite
a bit different from the reset flows in pdsc_fw_down()/pdsc_fw_up().
One key piece that's missing are the calls to pci_alloc_irq_vectors()
and pci_free_irq_vectors(). The pcie reset case is calling
pci_free_irq_vectors() on reset_prepare, but not calling the
corresponding pci_alloc_irq_vectors() on reset_done. This is causing
unexpected/unwanted interrupt behavior due to the adminq interrupt
being accidentally put into legacy interrupt mode. Also, the
pci_alloc_irq_vectors()/pci_free_irq_vectors() functions are being
called directly in probe/remove respectively.

Fix this inconsistency by making the following changes:
  1. Always call pdsc_dev_init() in pdsc_setup(), which calls
     pci_alloc_irq_vectors() and get rid of the now unused
     pds_dev_reinit().
  2. Always free/clear the pdsc->intr_info in pdsc_teardown()
     since this structure will get re-alloced in pdsc_setup().
  3. Move the calls of pci_free_irq_vectors() to pdsc_teardown()
     since pci_alloc_irq_vectors() will always be called in
     pdsc_setup()->pdsc_dev_init() for both the probe/remove and
     reset flows.
  4. Make sure to only create the debugfs "identity" entry when it
     doesn't already exist, which it will in the reset case because
     it's already been created in the initial call to pdsc_dev_init().

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.
