[PATCH 4.8 03/35] scsi: libfc: fix seconds_since_last_reset miscalculation

[Greg Kroah-Hartman]

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Johannes Thumshirn <jthumshirn@xxxxxxx>

commit 208da78e8ec8b6d6ce3747ab0e5c120458e08ae6 upstream.

Commit 540eb1eef0ab ("scsi: libfc: fix seconds_since_last_reset calculation")
removed the use of 'struct timespec' from fc_get_host_stats(). This broke the
output of 'fcoeadm -s' after kernel 4.8-rc1.
