From bc86fcee373f27bffc9ed0c0a734e40ec084aef5 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 4 Apr 2011 11:59:57 +0900 Subject: [PATCH] mfd: Continue with IRQ setup even if we don't have PMIC main IRQ The fact that we can't actually raise any interrupts doesn't stop us setting up the IRQs we're exporting. While this isn't actually going to do anything it allows us to proceed further through device setup during board bringup and avoids issues with the MFD core not letting us suppress the configuration of IRQ resources.
