From 7628774851751e55362ec7d9d57c9334e656a655 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Mon, 10 Jun 2013 17:03:40 +0200 Subject: mmc: core: Handle card shutdown from mmc_bus Considering shutdown of the card, the responsibility to initate this sequence shall be driven from the mmc_bus. This patch enables the mmc_bus to handle this sequence properly. A new .shutdown callback is added in the mmc_driver struct which is used to shutdown the blk device.
