A PCI controller device, e.g., StarFive, is parent to PCI host bridge device. We must enable runtime PM of the controller before enabling runtime PM of the host bridge, which will happen in pci_host_probe(), to avoid this warning: pcie-starfive 940000000.pcie: Enabling runtime PM for inactive device with active children Fix this issue by enabling StarFive controller device's runtime PM before calling pci_host_probe() in plda_pcie_host_init().

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.
