Hi, As Oliver pointed out we should not be returning USB specific error codes to user-space which currently almost all serial drivers do. The first two patches makes sure that all errors returned from serial_open in usb-serial are re-mapped using usb_translate_errors. The last five patches makes sure that all errors from the stack are actually forwarded to usb-serial core in open (some drivers returned -EPROTO rather than the valid -ENOMEM, for example). It's better to be consistent and do the re-map in one place for all drivers. Thanks, Johan Johan Hovold (7): USB: move usb_translate_errors to linux/usb.h USB: serial: do not forward USB specific errors in open USB: ch341: forward USB errors to USB serial core USB: cp210x: forward USB errors to USB serial core USB: iuu_phoenix: forward USB errors to USB serial core USB: oti6858: remove dead code USB: oti6858: forward USB errors to USB serial core drivers/usb/core/usb.h | 14 -------------- drivers/usb/serial/ch341.c | 2 +- drivers/usb/serial/cp210x.c | 19 +++++++++++++------ drivers/usb/serial/iuu_phoenix.c | 3 +-- drivers/usb/serial/oti6858.c | 14 +------------- drivers/usb/serial/usb-serial.c | 3 ++- include/linux/usb.h | 13 +++++++++++++ 7 files changed, 31 insertions(+), 37 deletions(-) -- 1.7.7.2 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
