From 476f8b4c94a90d1167961d90a5ed68dbe87c62da Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Thu, 4 Jun 2015 12:13:15 +0800 Subject: gpio: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we already have a pointer to corresponding irq_desc. Preparatory patch for the removal of the 'irq' argument from irq flow handlers.
