| |
From: Adam Kropelin <akropel1@rochester.rr.com>
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>.
