Subject: tty_ioctl: fix the baud_table check in encode_baud_rate
From: "Maciej W. Rozycki" <[EMAIL PROTECTED]>
The tty_termios_encode_baud_rate() function as defined by tty_ioctl.c has a
problem with the baud_table within. The comparison operators are reversed
and as a result this table's entries never match and BOTHER is always used.
