Geert Uytterhoeven ab8aa4f095 sh: mach-r2d: Handle virq offset in cascaded IRL demux ... When booting rts7751r2dplus_defconfig on QEMU, the system hangs due to an interrupt storm on IRQ 20. IRQ 20 aka event 0x280 is a cascaded IRL interrupt, which maps to IRQ_VOYAGER, the interrupt used by the Silicon Motion SM501 multimedia companion chip. As rts7751r2d_irq_demux() does not take into account the new virq offset, the interrupt is no longer translated, leading to an unhandled interrupt. Fix this by taking into account the virq offset when translating cascaded IRL interrupts.
