Subject: [PATCH] Device core: Remove dpm_sysfs_remove() from error path of device_add()

Hi Greg,

The appended patch fixes a bug in the error path of device_add().

Please accept it for 2.6.25.

Thanks,
Rafael

Since device_pm_remove(dev) calls dpm_sysfs_remove(dev), it's
incorrect to call the latter after the former in the device_add()
error path.
