From 75e8b71d559632dd70c9799ea8b5c133a2ddcea9 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Thu, 18 Oct 2007 03:04:35 -0700 Subject: [PATCH] tty_ioctl: fix the baud_table check in encode_baud_rate 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. Signed-off-by: Maciej W.
