parentnet: ethernet/sfc: Convert timers to use timer_setup() (diff)
net: dccp: Convert timers to use timer_setup()
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. Adds a pointer back to the sock. Cc: Gerrit Renker <gerrit@erg.abdn.ac.uk> Cc: "David S.
