+Subject: USB: pl2303: fixed handling of CS5 setting
+
+From: Colin Leitner <colin.leitner@googlemail.com>
+
+commit a313249937820f8b1996133fc285efbd6aad2c5b upstream.
+
+This patch fixes the CS5 setting on the PL2303 USB-to-serial devices. CS5 has a
+value of 0 and the CSIZE setting has been skipped altogether by the enclosing
+if. Tested on 3.11.6 and the scope shows the correct output after the fix has
+been applied.
+
+Tagged to be added to stable, because it fixes a user visible driver bug and is
+simple enough to backport easily.
