[ Upstream commit 527664f738afb6f2c58022cd35e63801e5dc7aec ] PCIe hotplug can operate in poll mode without interrupt handlers using a polling kthread only.eb34da60ed("PCI: pciehp: Disable hotplug interrupt during suspend") failed to consider that and enables HPIE (Hot-Plug Interrupt Enable) unconditionally when resuming the Port. Only set HPIE if non-poll mode is in use. This makes pcie_enable_interrupt() match how pcie_enable_notification() already handles HPIE.

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.
