Subject: [PATCH] cpufreq: Fix initialization with disabled boost
Date: Mon, 16 Jun 2025 18:25:43 +0100 [thread overview]
Message-ID: <3cc5b83b-f81c-4bd7-b7ff-4d02db4e25d8@arm.com> (raw)
The boost_enabled early return in policy_set_boost() caused
the boost disabled at initialization to not actually set the
initial policy->max, therefore effectively enabling boost while
it should have been enabled.
Fixes: 27241c8b63bd ("cpufreq: Introduce policy_set_boost()")
Reported-by: Robin Murphy <robin.murphy@arm.com>
