Tudor Ambarus ad7362db2f 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.

Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")
