Subject: [PATCH v11 01/20] timers: Restructure get_next_timer_interrupt()
Date: Wed, 21 Feb 2024 10:05:29 +0100

get_next_timer_interrupt() contains two parts for the next timer interrupt
calculation. Those two parts are separated by forwarding the base
clock. But the second part does not depend on the forwarded base
clock.

Therefore restructure get_next_timer_interrupt() to keep things together
which belong together.

No functional change.
