firmware: gsmi: remove sysfs entries when unload the module
This patch removes sysfs entries in gsmi_exit() and gsmi_init() error path. Also move the driver successfully loaded message to the end of gsmi_init() and return proper error if register_efivars() fails. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
