The patch titled
tty_ioctl: fix the baud_table check in encode_baud_rate
has been removed from the -mm tree. Its filename was
tty_ioctl-fix-the-baud_table-check-in-encode_baud_rate.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: tty_ioctl: fix the baud_table check in encode_baud_rate
From: "Maciej W. Rozycki" <macro@xxxxxxxxxxxxxx>
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.
