jsm: removing ch_old_baud field
Currently the field jsm_channel->ch_old_baud is not used, just assigned in a lot of places but never used. This patches removes this field. Signed-off-by: Breno Leitão <leitao@linux.vnet.ibm.com> Cc: Scott Kilau <scottk@digi.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
