Subject: [PATCH 0/7] Improvements to pci_endpoint_test driver

This series adds improvements and fixes to pci_endpoint_test driver
mostly applicable when used with multi-function endpoint (or multiple
endpoint instances using pci_epf_test).

*) Using module parameter to determine irqtype would indicate all the
   pci_endpoint_test device have the same irqtype. Fix it here.
*) Add ioctl to clear irq so that "cat /proc/interrupts" only lists
   the entries for the devices that is actually being used.
*) Creating more than 10 pci-endpoint-test devices results in a kernel
   error.
*) Use full pci-endpoint-test name in request irq so that it's easy to
   profile the interrupt details in "cat /proc/interrupts"
*) Always enable legacy interrupt.

Kishon Vijay Abraham I (7):
  misc: pci_endpoint_test: Avoid using module parameter to determine
    irqtype
  misc: pci_endpoint_test: Do not request or allocate IRQs in probe
  misc: pci_endpoint_test: Add ioctl to clear IRQ
  tools: PCI: Add 'e' to clear IRQ
  misc: pci_endpoint_test: Fix to support > 10 pci-endpoint-test devices
  misc: pci_endpoint_test: Use full pci-endpoint-test name in request
    irq
  misc: pci_endpoint_test: Enable legacy interrupt
