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 --- diff --git a/drivers/usb/serial/cp2101.c b/drivers/usb/serial/cp2101.c index f5b57b196c5a..2bc5576c443a 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];
