Subject: [PATCH v8 15/25] timer: Split next timer interrupt logic
Date:   Wed,  4 Oct 2023 14:34:44 +0200
Message-Id: <20231004123454.15691-16-anna-maria@linutronix.de>
In-Reply-To: <20231004123454.15691-1-anna-maria@linutronix.de>

Precedence: bulk

Logic for getting next timer interrupt (no matter of recalculated or
already stored in base->next_expiry) is split into a separate function
"next_timer_interrupt()" to make it available for new call sites.

No functional change.
