This looks fine, however it seems like we could either:

- update brcm_pcie_get_inbound_wins() to take a reference to an u8 and 
assign num_inbound_wins directly plus return a negative error code

or

- update brcm_pcie_get_inbound_wins() to return 0 when encountering an error

We should have at least 1 inbound window to operate this PCIe 
controller, so if we get 0, nothing useful is going to happen.

Deferring to Jim as to whether he prefers to take your patch or fix it 
in a different way. Thanks!
