From b2bdd1f5041db6f2d172417b5ceea20abc7a6eb6 Mon Sep 17 00:00:00 2001 From: Harvey Harrison Date: Fri, 30 May 2008 10:29:55 -0700 Subject: USB: cp2101.c fix sparse signedness mismatch warnings The get/set 2101_config helpers take an unsigned int rather than an int. It is safe to change these in each case and may even produce better code as it will be an unsigned divide rather than a signed divide in places. All other manipulation was setting/masking bits which will not be affected by the sign change. Fixes the following sparse warnings: drivers/usb/serial/cp2101.c:378:44: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:378:44: expected unsigned int *data drivers/usb/serial/cp2101.c:378:44: got int * drivers/usb/serial/cp2101.c:388:40: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:388:40: expected unsigned int *data drivers/usb/serial/cp2101.c:388:40: got int * drivers/usb/serial/cp2101.c:413:42: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:413:42: expected unsigned int *data drivers/usb/serial/cp2101.c:413:42: got int * drivers/usb/serial/cp2101.c:421:42: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:421:42: expected unsigned int *data drivers/usb/serial/cp2101.c:421:42: got int * drivers/usb/serial/cp2101.c:444:42: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:444:42: expected unsigned int *data drivers/usb/serial/cp2101.c:444:42: got int * drivers/usb/serial/cp2101.c:451:42: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:451:42: expected unsigned int *data drivers/usb/serial/cp2101.c:451:42: got int * drivers/usb/serial/cp2101.c:458:42: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:458:42: expected unsigned int *data drivers/usb/serial/cp2101.c:458:42: got int * drivers/usb/serial/cp2101.c:471:42: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:471:42: expected unsigned int *data drivers/usb/serial/cp2101.c:471:42: got int * drivers/usb/serial/cp2101.c:481:42: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:481:42: expected unsigned int *data drivers/usb/serial/cp2101.c:481:42: got int * drivers/usb/serial/cp2101.c:561:41: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:561:41: expected unsigned int *data drivers/usb/serial/cp2101.c:561:41: got int * drivers/usb/serial/cp2101.c:591:45: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:591:45: expected unsigned int *data drivers/usb/serial/cp2101.c:591:45: got int * drivers/usb/serial/cp2101.c:597:41: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:597:41: expected unsigned int *data drivers/usb/serial/cp2101.c:597:41: got int * drivers/usb/serial/cp2101.c:608:45: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:608:45: expected unsigned int *data drivers/usb/serial/cp2101.c:608:45: got int * drivers/usb/serial/cp2101.c:614:41: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:614:41: expected unsigned int *data drivers/usb/serial/cp2101.c:614:41: got int * drivers/usb/serial/cp2101.c:623:45: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:623:45: expected unsigned int *data drivers/usb/serial/cp2101.c:623:45: got int * drivers/usb/serial/cp2101.c:680:50: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:680:50: expected unsigned int *data drivers/usb/serial/cp2101.c:680:50: got int * drivers/usb/serial/cp2101.c:690:43: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:690:43: expected unsigned int *data drivers/usb/serial/cp2101.c:690:43: got int * drivers/usb/serial/cp2101.c:715:41: warning: incorrect type in argument 3 (different signedness) drivers/usb/serial/cp2101.c:715:41: expected unsigned int *data drivers/usb/serial/cp2101.c:715:41: got int * Signed-off-by: Harvey Harrison Signed-off-by: Greg Kroah-Hartman --- drivers/usb/serial/cp2101.c | 13 +++++++------ 1 file changed, 7 insertions(+), 6 deletions(-) (limited to 'drivers/usb/serial/cp2101.c') diff --git a/drivers/usb/serial/cp2101.c b/drivers/usb/serial/cp2101.c index f5b57b196c5..2bc5576c443 100644 --- a/drivers/usb/serial/cp2101.c +++ b/drivers/usb/serial/cp2101.c @@ -365,8 +365,8 @@ static void cp2101_close (struct usb_serial_port *port, struct file * filp) static void cp2101_get_termios (struct usb_serial_port *port) { unsigned int cflag, modem_ctl[4];

Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process.
