USB: removal of tty->low_latency hack dating back to the old serial code
commit 2400a2bfbd0e912193fe3b077f492d4980141813 upstream
[ cebbert@redhat.com: backport to 2.6.27 ]
USB: removal of tty->low_latency hack dating back to the old serial code
This removes tty->low_latency from all USB serial drivers that push
data into the tty layer at hard interrupt context. It's no longer needed
and actually harmful.
