Subject: [PATCH v6 6/6] ACPI: Set hotplug _OST support bit to _OSC
Date: Tue, 26 Jun 2012 14:42:54 -0600 [thread overview]
Message-ID: <1340743374-18535-7-git-send-email-toshi.kani@hp.com> (raw)
In-Reply-To: <1340743374-18535-1-git-send-email-toshi.kani@hp.com>
When ACPI_HOTPLUG_OST is defined, set hotplug _OST support bit
OSC_SB_HOTPLUG_OST_SUPPORT to indicate that the OS supports hotplug
_OST by calling the platform-wide ACPI Operating System Capabilities
(_OSC).
