#1541135 — [PATCH] greybus: timesync: replace init_timer with setup_timer

The combination of init_timer and setting up the data and function field
manually is equivalent to calling setup_timer(). This is an api 
consolidation only and improves readability.

 setup_timer.cocci suggested the following improvement:
 drivers/staging/greybus/timesync.c:1058:1-11: Use setup_timer function 
 for function on line 1059.

 Patch was compile checked with: x86_64_defconfig + CONFIG_STAGING=y, 
 CONFIG_GREYBUS=m

 Kernel version: 4.9.0 (localversion-next is next-20161213)
