+Subject: USB: ftdi_sio: fixed handling of unsupported CSIZE setting
+
+From: Colin Leitner <colin.leitner@googlemail.com>
+
+commit 8704211f65a2106ba01b6ac9727cdaf9ca11594c upstream.
+
+FTDI UARTs support only 7 or 8 data bits. Until now the ftdi_sio driver would
+only report this limitation for CS6 to dmesg and fail to reflect this fact to
+tcgetattr.
+
+This patch reverts the unsupported CSIZE setting and reports the fact with less
+severance to dmesg for both CS5 and CS6.
+
+To test the patch it's sufficient to call
+
+ stty -F /dev/ttyUSB0 cs5
+
+which will succeed without the patch and report an error with the patch
+applied.
+
+As an additional fix this patch ensures that the control request will always
+include a data bit size.

+
+From: Colin Leitner <colin.leitner@googlemail.com>
+
+commit 78692cc3382e0603a47e1f2aaeffe0d99891994d upstream.
+
+This patch removes an erroneous check of CSIZE, which made it impossible to set
+CS5.
+
+Compiles clean, but couldn't test against hardware.
