Drop erroneous cpu_to_le32 when setting the baud rate, something which corrupted the divisor on big-endian hosts. Found using sparse: warning: incorrect type in argument 1 (different base types) expected unsigned int [unsigned] [usertype] val got restricted __le32 [usertype] <noident> Fixes: af2ac1a091bc ("USB: serial mct_usb232: move DMA buffers to heap") Cc: stable <stable@xxxxxxxxxxxxxxx> # 2.6.34 Cc: Pete Zaitcev <zaitcev@xxxxxxxxxx> Signed-off-by: Johan Hovold <johan@xxxxxxxxxx> --- drivers/usb/serial/mct_u232.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/usb/serial/mct_u232.c b/drivers/usb/serial/mct_u232.c index edbc81f205c2..70f346f1aa86 100644 --- a/drivers/usb/serial/mct_u232.c +++ b/drivers/usb/serial/mct_u232.c @@ -189,7 +189,7 @@ static int mct_u232_set_baud_rate(struct tty_struct *tty, return -ENOMEM; divisor = mct_u232_calculate_baud_rate(serial, value, &speed); - put_unaligned_le32(cpu_to_le32(divisor), buf); + put_unaligned_le32(divisor, buf); rc = usb_control_msg(serial->dev, usb_sndctrlpipe(serial->dev, 0), MCT_U232_SET_BAUD_RATE_REQUEST, MCT_U232_SET_REQUEST_TYPE, -- 2.13.0
