Hey Alison,

Can you please elaborate that what do you mean by aligning on the basis
of rising and falling detection. Are you perhaps saying that I should
group the rising detection and group the falling detection separately?

To do this I should make the use of goto statement, right?

So the next patchset should be:
Patch 1: merge split lines
Patch 2: align on the basis of rising and falling detection
Patch 3: use goto statement to centralize unlock and return

Kindly guide me.

Regards,
Khadija
