MIPS: OCTEON: don't set octeon_dma_bar_type if PCI is disabled
commit dcf300a69ac307053dfb35c2e33972e754a98bce upstream. Don't set octeon_dma_bar_type if PCI is disabled. This avoids creation of the MSI irqchip later on, and saves a bit of memory. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Paul Burton <paul.burton@mips.com> Fixes: a214720cbf50 ("Disable MSI also when pcie-octeon.pcie_disable on") Cc: stable@vger.kernel.org # v3.3+ Cc: linux-mips@vger.kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
