Subject: [PATCH v1 4/7] ACPI: scan: Combine two conditionals in acpi_bus_attach()
Date: Mon, 31 Aug 2026 19:59:32 +0200 [thread overview]
Message-ID: <2021470.taCxCBeP46@rafael.j.wysocki> (raw)
In-Reply-To: <3435655.aeNJFYEL58@rafael.j.wysocki>
From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>
There are two conditionals in acpi_bus_attach() that can be combined,
which slightly reduces the overhead and makes the code a bit easier
to follow, so do that.
No intentional functional impact.
