[PATCH 5.4 06/19] net-sysfs: add a newline when printing tx_timeout by sysfs

[Greg Kroah-Hartman]

From: Xiongfeng Wang <wangxiongfeng2@xxxxxxxxxx>

[ Upstream commit 9bb5fbea59f36a589ef886292549ca4052fe676c ]

When I cat 'tx_timeout' by sysfs, it displays as follows. It's better to
add a newline for easy reading.

root@syzkaller:~# cat /sys/devices/virtual/net/lo/queues/tx-0/tx_timeout
0root@syzkaller:~#
