[PATCH] RDMA/i40iw: Convert timers to use timer_setup() (part 2)

From: Kees Cook
Date: Tue Oct 17 2017 - 14:38:04 EST


In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

This includes the remaining timers missed in the earlier i40iw patch.
