DMA devices are created during PCI probe of EAL init. These devices need

This patch adds the call to close() for all DMA devices.

Just to clarify the situation here - on EAL init, all buses are probed and
all devices initialized. On eal_cleanup/rte_exit the inverse does not
happen, then, i.e. all probed devices on all buses are not closed, right?
This would seem a better option than requiring each application to manually
close all devices even if it never used them. However, it is probably a
bigger and more complex change.
+1, precisely.
I've prepared an RFC to explore option of adding bus cleanup to
eal_cleanup() to start a discussion on that option.
