Perf will use a similar method to the PCI sub driver to register the PMUs for the PCI type of uncore blocks. The method requires a BUS notifier to support hotplug. The current BUS notifier cannot be reused, because it searches a const id_table for the corresponding registered PMU. The PCI type of uncore blocks in the discovery tables doesn't provide an id_table. Factor out uncore_bus_notify() and add the pointer of an id_table as a parameter. The uncore_bus_notify() will be reused in the following patch. The current BUS notifier is only used by the PCI sub driver. Its name is too generic. Rename it to uncore_pci_sub_notifier, which is specific for the PCI sub driver.

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.
