Subject: bus/pci: fix memory leak when unmapping VFIO resource
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e34a43a6729dd33e430e1815a395893fe1c643d6;p=dpdk.git

bus/pci: fix memory leak when unmapping VFIO resource

The 'vfio_res' is not freed when unmapping resource by primary process.
This leads to memory leak.

Fixes: ab53203e194b ("vfio: enable unmapping resource for secondary")
