From 2e550b6d277bdf5daf579bb7952d1b183ff0948a Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Fri, 27 May 2016 20:15:55 +0530 Subject: [PATCH] ath10k: fix operating irq mode for ahb device Earlier when operating irq mode is legacy, interrupts are disabled and re-enabled based on num_msi_intrs. commit cfe9011a05a8 ("ath10k: remove MSI range support") replaced num_msi_intrs by oper_irq_mode. Since oper_irq_mode is not initialized for ahb devices (i.e qca4019), device boot up is failed during probe.
