From 1e4de81653bae3f5e6d06e3384853d31d564bbec Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Wed, 29 Jun 2011 15:57:53 +0800 Subject: 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.
