From dece904d74800d109f1bb06b55758169b1bcc140 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 9 Dec 2011 14:12:53 -0600 Subject: [PATCH] gpio: pl061: use chained_irq_* functions in irq handler Use chained_irq_enter/exit helper functions instead of direct pointer accesses. This is needed for generic irq chip conversion.
