From e2d1926bad0d0cf7e4b8bf11a8efd1b5fe48893e Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Thu, 18 Dec 2014 15:44:35 +0100 Subject: [PATCH] mmc: core: Free all resources for the class device at ->dev_release() To be consistent when freeing data, let's move the idr_remove() call from mmc_free_host() into the ->dev_release() callback for the class device.
