From 8614419451d88bf99fff7f5e468fe45f8450891e Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Sun, 13 May 2012 18:53:23 +0100 Subject: [PATCH] mfd: da9052: Fix genirq abuse Rather than using the pointer passed back by the regmap API (or complaining because that wasn't actually being set) the da9052 driver was having some fun and games peering through genirq and regmap internals. Fix the driver to use the API as expected.
