Subject: [PATCH 5.10 287/717] clocksource/drivers/ingenic: Fix section mismatch

From: Daniel Lezcano <daniel.lezcano@...aro.org>

[ Upstream commit 5bd7cb29eceb52e4b108917786fdbf2a2c2048ef ]

The function ingenic_tcu_get_clock() is annotated for the __init
section but it is actually called from the online cpu callback.

That will lead to a crash if a CPU is hotplugged after boot time.

Remove the __init annotation for the ingenic_tcu_get_clock()
function.

Fixes: f19d838d08fc (clocksource/drivers/ingenic: Add high resolution timer support for SMP/SMT)
