[PATCH 2.6.13-rc3-git9] pl2303: pl2303_update_line_status data length fix

[Horst Schirmeier]

Minimum data length must be UART_STATE + 1, as data[UART_STATE] is being
accessed for the new line_state. Although PL-2303 hardware is not
expected to send data with exactly UART_STATE length, this keeps it on
the safe side.
