Subject: [PATCH v5 08/18] ACPI: convert acpi_processor_post_eject() to use IS_ENABLED()
Date: Fri, 12 Apr 2024 15:37:09 +0100 [thread overview]
Message-ID: <20240412143719.11398-9-Jonathan.Cameron@huawei.com> (raw)
In-Reply-To: <20240412143719.11398-1-Jonathan.Cameron@huawei.com>
From: Russell King <rmk+kernel@armlinux.org.uk>
Rather than ifdef'ing acpi_processor_post_eject() and its use site, use
IS_ENABLED() to increase compile coverage.
