generic_serial: fix decoding of baud rate
Commit d720bc4b8fc5d6d179ef094908d4fbb5e436ffad partially removed a private implementation of baud speed decoding. However it doesn't seem to be complete: after the speed is decoded, it is still being used as an index to a local speed table (array overrun, no doubt). This was found by Graham Murray who noticed it caused a 2.6.19 regression with the SX driver: https://bugs.gentoo.org/170554 Signed-off-by: Daniel Drake <dsd@gentoo.org> Acked-by: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
