+Subject: spi: mediatek: use correct mata->xfer_len when in fifo transfer
+
+From: Leilk Liu <leilk.liu@mediatek.com>
+
+commit a4d8f64f7267a88d4688f5c216926f5f6cafbae6 upstream.
+
+when xfer_len is greater than 64 bytes and use fifo mode
+to transfer, the actual length from the third time is mata->xfer_len
+but not len in mtk_spi_interrupt().

+Subject: tee: optee: add missing of_node_put after of_device_is_available
+
+From: Julia Lawall <Julia.Lawall@lip6.fr>
+
+commit c7c0d8df0b94a67377555a550b8d66ee2ad2f4ed upstream.
+
+Add an of_node_put when a tested device node is not available.
+
+The semantic patch that fixes this problem is as follows
+(http://coccinelle.lip6.fr):
+
+// <smpl>
+@@
+identifier f;
+local idexpression e;
+expression x;
+@@
+
+e = f(...);
+... when != of_node_put(e)
+    when != x = e
+    when != e = x
+    when any
+if (<+...of_device_is_available(e)...+>) {
+  ... when != of_node_put(e)
+(
+  return e;
+|
++ of_node_put(e);
+  return ...;
+)
+}
+// </smpl>
