[PATCH] irqchip: omap-intc: fix legacy DMA regression

2015-01-06 Thread Felipe Balbi
commit 55601c9f2467 (arm: omap: intc: switch over to linear irq domain) introduced a regression with SDMA legacy driver because that driver strictly depends on INTC's IRQs starting at NR_IRQs. Aparently irq_domain_add_linear() won't guarantee that, since we see a 7 IRQs difference when booting with
