[PATCH] staging: i4l: icn: use setup_timer() and mod_timer().

From: Muhammad Falak R Wani
Date: Wed May 11 2016 - 09:30:21 EST


Use setup_timer() instead of init_timer(), being the preferred/standard
way to set a timer up.

Also, quoting the mod_timer() function comment:
-> mod_timer() is a more efficient way to update the expire field of an
active timer (if the timer is inactive it will be activated).

Use setup_timer and mod_timer to setup and arm a timer, to make the code
cleaner and easier to read.
