Revision a69bf3c5b49ef488970c74e26ba0ec12f08491c2 authored by Douglas Miller on 04 March 2016, 21:36:56 UTC, committed by David S. Miller on 07 March 2016, 20:18:31 UTC 
be2net: Don't leak iomapped memory on removal.
 
The adapter->pcicfg resource is either mapped via pci_iomap() or
derived from adapter->db. During be_remove() this resource was ignored
and so could remain mapped after remove.

Add a flag to track whether adapter->pcicfg was mapped or not, then
use that flag in be_unmap_pci_bars() to unmap if required.

Fixes: 25848c901 ("use PCI MMIO read instead of config read for errors")
