Subject: [PATCH 2/4] Drivers: hv: allow non ACPI compilation for hv_is_hibernation_supported
Date: Mon, 16 Jan 2023 08:48:06 -0800 [thread overview]
Message-ID: <1673887688-19151-3-git-send-email-ssengar@linux.microsoft.com> (raw)
In-Reply-To: <1673887688-19151-1-git-send-email-ssengar@linux.microsoft.com>
acpi_sleep_state_supported API is only define for CONFIG_ACPI flag and
thus it can't be used for non-ACPI builds. Initaly there won't be
hibernate support for non ACPI builds.
This change will help adding device tree support in subsequent commits.
