Subject: [PATCH 3/4] x86/boot/compressed: Mark process_mem_region() index __maybe_unused
Date: Sun, 21 Jun 2026 16:41:20 +0200 [thread overview]
Message-ID: <20260621144116.224010-9-thorsten.blum@linux.dev> (raw)
In-Reply-To: <20260621144116.224010-6-thorsten.blum@linux.dev>
The local index variable i in process_mem_region() is unused when either
CONFIG_MEMORY_HOTREMOVE or CONFIG_ACPI is disabled.
Mark it __maybe_unused accordingly.
