USB: serial: kl5kusb105: abort on open exception path commit 3c3dd1e058cb01e835dcade4b54a6f13ffaeaf7c upstream. Function klsi_105_open() calls usb_control_msg() (to "enable read") and checks its return value. When the return value is unexpected, it only assigns the error code to the return variable retval, but does not terminate the exception path. This patch fixes the bug by inserting "goto err_generic_close;" when the call to usb_control_msg() fails.
