From 5c7f0e083d2d98ba14ddd10e88f001a0ead4cae4 Mon Sep 17 00:00:00 2001 From: Ohad Ben-Cohen Date: Mon, 19 Dec 2011 15:51:38 -0800 Subject: Revert "mmc: enable runtime PM by default" When SDIO runtime PM was originally introduced, we immediately faced two regressions with two different chipsets, and in response decided not to enable it by default. 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.
