From 2501c9179dff2add6aadd3898cd729e94e777d3a Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Wed, 30 Oct 2013 01:00:18 +0100 Subject: mmc: core: Use MMC_UNSAFE_RESUME as default behavior Invoking system suspend or shutdown without using the Kconfig option MMC_UNSAFE_RESUME, did trigger an ungraceful power cut of the card. To improve the situation, change the behavior to always make use of the available bus_ops callbacks that handles system suspend and shutdown properly. By changing the behavior MMC_UNSAFE_RESUME becomes redundant, so lets's remove it.
