Krzysztof WilczyńskiandGreg Kroah-Hartman 9ff90fdf84 alpha/PCI: Fix __pci_mmap_fits() overflow for zero-length BARs ...

[ Upstream commit 802a3b3f47 ]

Currently, __pci_mmap_fits() computes the BAR size using
"pci_resource_len() - 1", which wraps to a large value when the BAR length
is zero, causing the bounds check to incorrectly succeed.

Add an early return for empty resources.
