Changes for v1
- Drop non-initialize changes.

- Use request_irq.
Hi Yoshinori,
thanks for the changes.
Unfortunately, they don't apply.
You should base your changes on top of:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git tip/timers/core
In order to have the latest changes with the h8300. One of them in the
removal of the memset.
Regards
