Subject: [PATCH 13/14] drivers/firmware/sdei: Retrieve event signaled property on creation
Date: Mon,  6 Jul 2020 15:47:31 +1000	[thread overview]
Message-ID: <20200706054732.99387-14-gshan@redhat.com> (raw)
In-Reply-To: <20200706054732.99387-1-gshan@redhat.com>

This retrieves the event signaled property when it's created for the
first time. The property will be needed when SDEI virtualization is
supported.
