Subject: [PATCH 24/39] ACPI: Move acpi_bus_trim_one() before acpi_scan_hot_remove()
Date: Tue, 24 Oct 2023 16:18:12 +0100 [thread overview]
Message-ID: <E1qvJAa-00AqRA-Pt@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <ZTffkAdOqL2pI2la@shell.armlinux.org.uk>
From: James Morse <james.morse@arm.com>
A subsequent patch will change acpi_scan_hot_remove() to call
acpi_bus_trim_one() instead of acpi_bus_trim(), meaning it can no longer
rely on the prototype in the header file.
Move these functions further up the file.
No change in behaviour.
