Subject: generic_serial: fix decoding of baud rate
From: Daniel Drake <dsd@xxxxxxxxxx>
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
