Subject: [PATCH 1/2] platform/surface: aggregator: Add missing call to ssam_request_sync_free()
Date:   Tue, 20 Dec 2022 18:56:07 +0100

Although rare, ssam_request_sync_init() can fail. In that case, the
request should be freed via ssam_request_sync_free(). Currently it is
leaked instead. Fix this.
