`setup_timer` is no longer available in kernel 4.15 and onwards,
in favor of `timer_setup`.
Before, we could pass an argument to the callback function as an
unsigned int (generally used with a pointer cast), but now the timer
itself is passed and we retrieve the container struct with a new
macro `from_timer` which is uses `container_of`.
The flags parameter can be set as 0 for the same behavior.
