| In reply to | #1724645 |
This standardizes the callback and data prototypes in several places that
perform casting, in an effort to remove more open-coded .data and
.function uses in favor of setup_timer().

In several places, .data is checked for initialization to gate early
calls to del_timer_sync(). Checking for .function is equally valid, so
switch to this in all callers.
