| Subject: irqchip: orion: use handle_edge_irq on bridge irqs |
| |
| From: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> |
| |
| commit 5f40067fc86f0e49329ad4a852c278998ff4394e upstream. |
| |
| Bridge irqs are edge-triggered, i.e. they get asserted on low-to-high |
| transitions and not on the level of the downstream interrupt line. |
| This replaces handle_level_irq by the more appropriate handle_edge_irq. |
