Subject: [PATCH v4 2/6] Drivers: hv: allow non ACPI compilation for hv_is_hibernation_supported
Date:   Mon,  6 Feb 2023 23:49:55 -0800
Message-Id: <1675756199-5917-3-git-send-email-ssengar@linux.microsoft.com>
In-Reply-To: <1675756199-5917-1-git-send-email-ssengar@linux.microsoft.com>

Precedence: bulk

acpi_sleep_state_supported API is only define for CONFIG_ACPI flag and
thus it can't be used for non-ACPI builds. Initially there won't be
hibernation support for non ACPI builds.

This change will help adding device tree support in subsequent commits.
