Subject: bcma: reject PCI cards in bcma.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dfa0415bcbc606bd20c63d3119ed00839280690a;p=linux-beck.git

bcma: reject PCI cards in bcma.

bcma currently only supports PCIe cards and no PCI cards, reject them
if we find them. I have never heard of any PCI card using the AI bus
(bcma), all of them are using ssb instead.
