Subject: [PATCH v3 06/22] ACPI: platform_profile: Move sanity check out of the mutex
Date: Wed, 30 Oct 2024 23:09:36 -0500 [thread overview]
Message-ID: <20241031040952.109057-7-mario.limonciello@amd.com> (raw)
In-Reply-To: <20241031040952.109057-1-mario.limonciello@amd.com>
The sanity check that the platform handler had choices set doesn't
need the mutex taken. Move it to earlier in the registration.
Tested-by: Matthew Schwartz <matthew.schwartz@linux.dev>
