usb-serial: Fix edgeport regression on non-EPiC devices
Fix serious regression on non-EPiC edgeport usb-serial devices. Baud rate and MCR/LCR registers are not being written on these models due to apparent copy-n-paste errors introduced with EPiC support. Failure reported by Nick Pasich <Nick@NickAndBarb.net>. Signed-off-by: Adam Kropelin <akropel1@rochester.rr.com> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
