+Subject: USB: serial: cp210x: enable usb generic throttle/unthrottle
+
+From: Brant Merryman <brant.merryman@silabs.com>
+
+commit 4387b3dbb079d482d3c2b43a703ceed4dd27ed28 upstream
+
+Assign the .throttle and .unthrottle functions to be generic function
+in the driver structure to prevent data loss that can otherwise occur
+if the host does not enable USB throttling.
