From 7fdb5d32614f7784fc7c2b8e883eb4da26358a94 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Sun, 3 Jun 2012 13:37:23 +0100 Subject: mfd: Rely on regmap cache in wm8350 interrupt controller We can just use regmap_update_bits() to achieve the same effect - it will do the read/modify/update cycle for us.
