->get_msi() now checks MSI_EN bit in the MSI CAPABILITY register to
find whether the host supports MSI instead of using the
MSI ADDRESS in the MSI CAPABILITY register.
This fixes the issue with the following sequence
'modprobe pci_endpoint_test' enables MSI
'rmmod pci_endpoint_test' disables MSI but MSI address (in EP's
capability register) has a valid value
'modprobe pci_endpoint_test no_msi=1' - Since MSI address (in EP's
capability register) has a valid value (set during the previous
insertion of the module), EP thinks host supports MSI.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
