Subject: USB: digi_acceleport: fix termios and also readability a bit
X-Git-Tag: v2.6.24-rc2~136^2~34
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=7fa36a994cb4298f29994a248ced831be8dc7051;p=linux-2.6-omap-h63xx.git

USB: digi_acceleport: fix termios and also readability a bit

- Expand some x&y to x & y so I could read it when checking
- Clear CMSPAR bit in the termios (as the driver does not support it)
- Encode the speed using the new tty_encode_baud_rate facility
