Subject: [PATCH 4.4 104/143] MIPS: OCTEON: dont set octeon_dma_bar_type if PCI is disabled
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Aaro Koskinen <aaro.koskinen@....fi>
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.
