From 325255bc9554504a2545284655d4fd8e74c06c22 Mon Sep 17 00:00:00 2001 From: Kiran Gunda Date: Fri, 28 Jul 2017 12:40:39 +0530 Subject: [PATCH] spmi: pmic-arb: optimize qpnpint_irq_set_type function Optimize the qpnpint_irq_set_type() by using a local variable to hold the handler type. Also clean up other variable usage.
