USB: serial: cp210x.c: remove dbg() usage
dbg() was a very old USB-serial-specific macro. This patch removes it from being used in the driver and uses dev_dbg() instead. CC: Johan Hovold <jhovold@gmail.com> CC: Preston Fick <preston.fick@silabs.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
