[S390] tape: duplicate sysfs filename when setting tape device online
When a tape device is set online, offline and online again, the following error message is printed on the console: "sysfs: duplicate filename 'non-rewinding' can not be created". The reason is that when setting a device online, the tape driver creates a sysfs symlink from the tape device to the tape class device. Unfortunately the symlink is not removed correctly, when the device is set offline. Instead of passing the tape device object to sysfs_remove_link, the class device object is used. This patch fixes this problem and uses the correct tape device object now.
