From 29495aa04a30c21565243c5b9c028510446d242c Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Thu, 3 Nov 2011 11:09:45 +0100 Subject: [PATCH 1/3] mmc: sdhci: remove "state" argument from sdhci_suspend_host Drop the "state" argument from sdhci_suspend_host. Its only user is the PCI glue; this allows to move all SDHCI glues to use dev_pm_ops instead.

With the recent work on the 8686 we hoped we found all the gotchas, so 08da834 did make sense (at least experimentally). Unfortunately we now see that some setups out there still refuse to work when SDIO runtime PM is enabled by default (see http://www.spinics.net/lists/linux-mmc/msg11161.html), and obviously we can't live with these kind of regressions. This reverts commit 08da834a24312157f512224691ad1fddd11c1073.
