Compare what remove_host does and > what add_host does before it fails. What do you think? Ok..i'm looking at the mmc-core code(host.c) mmc_add_host does devices_add(), then run start_host(). mmc_remove_host does stop_host(). You means that didn't run start_host() before add_host failed. I think that need not to run stop_host. right? To use mmc_free_host, better than mmc_remove_host.
