+Subject: [PATCH 1/1] lenovo/t400: Enable all SATA ports
+
+There are 2 SATA ports on the chassis of t400(s), but at least one dock for
+t400 contains a port for (P/S)ATA device, and t400s has a eSATA port on its
+chassis, and another one on its dock.
+
+They have to be unmasked via device tree to use.
+
+This patch unmasked all SATA ports found within t400s with factory firmware.
