| Subject: Dove: Fix irq_to_pmu() |
| |
| From: Russell King - ARM Linux <linux@arm.linux.org.uk> |
| |
| commit d356cf5a74afa32b40decca3c9dd88bc3cd63eb5 upstream. |
| |
| PMU interrupts start at IRQ_DOVE_PMU_START, not IRQ_DOVE_PMU_START + 1. |
| Fix the condition. (It may have been less likely to occur had the code |
| been written "if (irq >= IRQ_DOVE_PMU_START" which imho is the easier |
| to understand notation, and matches the normal way of thinking about |
| these things.) |
