Also cleans up a few unnecessary constructs related to this change: return xx ? 1 : 0; -> return xx; if (xx) return 1; return 0; -> return xx; Signed-off-by: Ilpo Järvinen Reviewed-by: Jiri Slaby --- drivers/char/pcmcia/synclink_cs.c | 8 +++----- drivers/mmc/core/sdio_uart.c | 7 +++---- drivers/tty/amiserial.c | 2 +- drivers/tty/moxa.c | 4 ++-- drivers/tty/mxser.c | 5 +++-- drivers/tty/n_gsm.c | 8 ++++---- drivers/tty/serial/serial_core.c | 9 ++++----- drivers/tty/synclink_gt.c | 7 ++++--- drivers/tty/tty_port.c | 4 ++-- drivers/usb/serial/ch341.c | 7 +++---- drivers/usb/serial/f81232.c | 6 ++---- drivers/usb/serial/pl2303.c | 7 ++----- drivers/usb/serial/spcp8x5.c | 7 ++----- drivers/usb/serial/usb-serial.c | 4 ++-- include/linux/tty_port.h | 6 +++--- include/linux/usb/serial.h | 2 +- net/bluetooth/rfcomm/tty.c | 2 +- 17 files changed, 42 insertions(+), 53 deletions(-) diff --git a/drivers/char/pcmcia/synclink_cs.c b/drivers/char/pcmcia/synclink_cs.c index baa46e8a094b..4391138e1b8a 100644 --- a/drivers/char/pcmcia/synclink_cs.c +++ b/drivers/char/pcmcia/synclink_cs.c @@ -377,7 +377,7 @@ static void async_mode(MGSLPC_INFO *info);

The parameter is used like bool. In USB serial, there remains a few implicit bool -> larger type conversions because some devices use u8 in their control messages.
