From 4b5ce20b5429eb08ae0776962a4aff7f00017800 Mon Sep 17 00:00:00 2001 From: Milo Kim Date: Wed, 13 Jan 2016 16:19:52 +0900 Subject: [PATCH] irqchip/atmel-aic: Remove duplicate bit operation AIC5 priority value is updated twice - in aic_common_set_priority() and when updating AT91_AIC5_SMR. Variable, 'smr' has updated priority value (intspec[2]) in the first step, so no need to update it again in the second step.
