From b1e952b4e484ebc9ffad674c361d261a1af02a13 Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Mon, 24 Nov 2014 10:41:56 +0100 Subject: arm/arm64: vgic: Remove unreachable irq_clear_pending When 'injecting' an edge-triggered interrupt with a falling edge we shouldn't clear the pending state on the distributor. In fact, we don't, because the check in vgic_validate_injection would prevent us from ever reaching this bit of code. Remove the unreachable snippet.
