3.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Junjie Mao <junjie_...@yeah.net>
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.
Fixes: fa6fdb33b486 ("driver core: bus_type: add dev_groups")
