Tudor Ambarus c220378081 tty: serial: samsung: fix tx_empty() to return TIOCSER_TEMT ... [ Upstream commit 314c2b3992 ] The core expects for tx_empty() either TIOCSER_TEMT when the tx is empty or 0 otherwise. s3c24xx_serial_txempty_nofifo() might return 0x4, and at least uart_get_lsr_info() tries to clear exactly TIOCSER_TEMT (BIT(1)). Fix tx_empty() to return TIOCSER_TEMT.
