Subject: USB: digi_acceleport further buffer clean up
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5fea2a4dabdfa1ad59845c42ea770ee8cb41ecad;p=openwrt%2Fstaging%2Fblogic.git

USB: digi_acceleport further buffer clean up

Some further cleanup after Oliver's patch to update the tty
buffering.  The input buffer is not used at all anymore, so
I removed it.
