Subject: [PATCH 07/24] can: Switch to use hrtimer_setup()
There is a newly introduced hrtimer_setup() which will replace
hrtimer_init(). This new function is similar to the old one, except that it
also sanity-checks and initializes the timer's callback function.
Switch to use this new function.
Patch was created by using Coccinelle.
