[PATCH v2 0/3] Fix IDXD PCI device close

This patchset addresses the device close for IDXD PCI devices.
Initially, there was a memory leak reported by ASAN for the 'pci' member
of the 'idxd_dmadev' struct due to a missing free. In addition, this
patch set corrects the behaviour of the device close function to ensure
the cleanup is completed correctly.

Depends-on: patch-112376 ("eal: add device removal in rte cleanup")

---
v2:
* remove changes to applications (no longer needed with EAL changes)
* add fix for NULL pointer dereference in pci remove

Kevin Laatz (3):
  dma/idxd: fix memory leak in pci close
  dma/idxd: fix memory leak due to free on incorrect pointer
  dma/idxd: fix null pointer dereference during pci remove
