From df508450870cd5b4478156dcde8e68e6bf0d6661 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 14 Jan 2011 13:38:16 +0000 Subject: [PATCH] mfd: Leave acknowledgement of WM831x touchscreen IRQs to the driver The WM831x touchscreen interrupts need acknowledgement even when using direct signals to the CPU (which don't go through the core) so leave the acknowledgement up to the touchscreen driver for simplicity.
