+Subject: 3w-9xxx: fix command completion race
+
+From: Christoph Hellwig <hch@lst.de>
+
+commit 118c855b5623f3e2e6204f02623d88c09e0c34de upstream.
+
+The 3w-9xxx driver needs to tear down the dma mappings before returning
+the command to the midlayer, as there is no guarantee the sglist and
+count are valid after that point. Also remove the dma mapping helpers
+which have another inherent race due to the request_id index.

+Subject: usb: host: oxu210hp: use new USB_RESUME_TIMEOUT
+
+From: Felipe Balbi <balbi@ti.com>
+
+commit 84c0d178eb9f3a3ae4d63dc97a440266cf17f7f5 upstream.
+
+Make sure we're using the new macro, so our
+resume signaling will always pass certification.
