From a55b316e02dda9ffd7ef5ebb04962607f669baae Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 30 Jun 2012 15:16:04 +0200 Subject: brcmsmac: remove PCIE() macro Instead of checking if there is a PCIe core on the bus, better check if hosttype is PCIe. In the original submission to staging PCIE() checked, if the bustype is PCI and the buscore is a PCIe core. Now we assume that all cores bcma supports are PCIe based, so we just have to check if the bustype is PCI. The old code bcmsmac currently uses searches for a PCIe core on the bus and if there is one assumes that this is the buscore, which is wrong. Some SoCs have a PCIe core operating in host mode and this is not the bus core. The old code also caused a null pointer in ai_get_buscoretype() and ai_get_buscorerev() if buscore was not set because there was no PCIe core on the bus.
