bcma: lower dependency of BCMA_DRIVER_PCI_HOSTMODE 2015-06-08T11:33:26+00:00 Rafał Miłecki zajec5@gmail.com 2015-06-07T11:15:31+00:00 49280625eb826ab07882e91fb84023a54317317f This extension of BCMA_DRIVER_PCI has no reason to depend on BCMA_HOST_PCI. User may just want to have PCI device attached to SoC registered without enabling any extra client mode code. This can be useful when having non-bcma PCI device attached or when using other PCI driver. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
