Hi Claudiu,

I love your patch! Yet something to improve:

[auto build test ERROR on tip/timers/core]
[also build test ERROR on soc/for-next linus/master v5.17-rc6 next-20220225]
[cannot apply to daniel-lezcano/clockevents/next]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
https://git-scm.com/docs/git-format-patch]
