>From 762c60b2545dc55c0a6276b32dd5930d0ae65ada Mon Sep 17 00:00:00 2001 From: Ohad Ben-Cohen <[email protected]> Date: Wed, 11 Aug 2010 11:18:33 +0300 Subject: [PATCH 19/26] sdio: use the generic runtime PM handlers
Assign the generic runtime PM handlers for SDIO. These handlers invoke the relevant SDIO function drivers' handlers, if exist, otherwise they just return success (so SDIO drivers don't have to define any runtime PM handlers unless they need to). Runtime PM is still disabled by default, so this patch alone has no immediate effect.
