From 800791e7e0fd9835be2f55c55147c379888b7442 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Tue, 14 Mar 2017 08:23:26 -0700 Subject: [PATCH] pinctrl: qcom: Don't clear status bit on irq_unmask commit a6566710adaa4a7dd5e0d99820ff9c9c30ee5951 upstream. Clearing the status bit on irq_unmask will discard any pending interrupt that did arrive after the irq_ack, i.e. while the IRQ handler function was executing.
