3.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: "Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx>" commit b530f742ac27460d41d35b638ad6aad92044a982 upstream. Due to NR_IRQS being incorrectly defined not all IRQ domains can be registered for S3C2440. It causes following errors on a s3c2440 SoC based board: NR_IRQS:89 S3C2440: IRQ Support irq: clearing pending status 00000002 ------------[ cut here ]------------ WARNING: at kernel/irq/irqdomain.c:234 0xc0056ed0() ... irq: could not create irq-domain ... s3c2410-wdt s3c2410-wdt: failed to install irq (-22) s3c2410-wdt: probe of s3c2410-wdt failed with error -22 ... samsung-uart s3c2440-uart.0: cannot get irq 74 Fix this by increasing NR_IRQS to at least (IRQ_S3C2443_AC97 + 1) if CPU_S3C2440 is selected, so the subintc IRQ domain gets properly registered.
