If anyone has any objections, please let me know. ------------------ From: Junjie Mao commit 1c34203a1496d1849ba978021b878b3447d433c8 upstream. It is not necessary to call device_remove_groups() when device_add_groups() fails. The group added by device_add_groups() should be removed if sysfs_create_link() fails.
