This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Char: moxa, variables cleanup
From: Jiri Slaby <jirislaby@gmail.com>
- rename moxaChannels to moxa_port
- rename moxa_str to moxa_ports
- move board global variables into moxa_board
- move port global variables into moxa_port
