From fe64ac89cf8f5067cf7f6757b6cd9fd77c527bdf Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 19 Jun 2014 21:34:43 +0000 Subject: irqchip: spear_shirq: Remove the parent irq "ack"/unmask "ack" is actually a mask in the parent irq. The demultiplexer and the handlers run with interrupts disabled. No point in masking and unmasking the parent.
