Subject: [PATCH v1 02/10] platform/x86: classmate-laptop: Unify probe rollback and remove code
Date: Thu, 07 May 2026 22:01:16 +0200	[thread overview]
Message-ID: <3410625.aeNJFYEL58@rafael.j.wysocki> (raw)
In-Reply-To: <1956046.tdWV9SEqCh@rafael.j.wysocki>

From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>

To facilitate subsequent modifications, change code ordering in
cmpc_accel_add_v4(), cmpc_accel_add(), and  cmpc_accel_remove_v4()
so that the ordering of the probe rollback code is the same as the
ordering of the corresponding removal code.

No intentional functional impact.
